A settling tank has an influent rate of 0.6 mgd. It is 12 ft deep and has a surface area of 8000 ft². What is the hydraulic retention time?
Answers
Answer: hydraulic retention time,τ=28.67 hours
Explanation:
The hydraulic retention time τ (tau), is given as The volume of the settling tank(V) divided by the influent flowrate(Q)
τ =V/Q
But Volume is not known and is given as
Volume = surface area x depth of the tank
= 8000 ft² X 12 ft
= 96,000 ft³
Also, the influent flow rate is in mgd ( million gallons per day), we change it to ft³/sec so as to be in same unit with the volume in ft³
1 million gallons/day = 1.5472286365101 cubic feet/second
0.6mgd = 1.5472286365101 cubic feet/second x 0.6
=0.93cubic feet/second
τ =V/Q
96,000 ft³/0.93 ft³/sec
τ=103,225.8 secs
changing to hours
103,225.8 /3600 =28.67 hours
The hydraulic retention time =28.67 hours

Two wooden members of uniform rectangular cross section are joined using a simple glued scarf splice. The maximum allowable shearing stress and maximum allowable normal stress in the glued splice is 50 MPa and 100 MPa, respectively. The cross-section area of the glued member is 400 mm2. (a) What should the value of the angle be to achieve maximum load Fmax? (b) What is the magnitude of the maximum load Fmax?
Answers
Answer:
a). α = 26.57
b). Maximum load is 50 .kN
Explanation:
a).
The normal force is given by
N = σ A cosec β
where, σ is the normal stress
A is the cross sectional area
Similarly, shear force is given by
S= τ A cosec β
where, τ is the shearing stress
Now from the figure,
tan β = S/N
= τ/σ
Therefore, \($\beta = \tan^{-1}(2)$\) = 63.43
α = 90 - β = 26.57
b).
The normal force is given by
\($N=(100\times 10^6)(400\times 10^{-6}) \text{ cosec}\ 63.43$\)
\($N=44.78\times 10^3$\) N
We have
\($\Sigma F_y=0$\)
∴ N - F sin β = 0
⇒ F = N / sin β
= \($\frac{44.72\times 10^3}{\sin(63.43)} = 50\times 10^3 N$\)
Similarly,
The shear force is given by
S = τ A cosec β
= \($(50\times 10^6)(400\times 10^{-6}) \text{ cosec}\ 63.43 = 22.36\times 10^3 N$\)
\($\Sigma F_x=0$\)
∴ S - F cos β = 0
⇒ F = S / cos β
\($\frac{22.36\times 10^3}{\cos(63.43)} = 49.99\times 10^3 N$\)
Therefore, force is 50 kN.

Answers
To order the given functions by their growth rate and group them based on their asymptotic behavior, we can follow these steps: 1. Group the functions based on the same growth rate or complexity class.
2. Within each group, order the functions in ascending order based on their growth rate.
Here's the ordered list with the functions grouped by their complexity class:
Group 1:
- ln ln n
Group 2:
- (lg n)/(lg lg n)
- (n lg lg n)
Group 3:
- (lg n)2

Group 5:
- n lg n
Group 6:

The algorithm is correct because it correctly groups the functions based on their complexity classes and orders them within each group in ascending order. The functions within each group have similar asymptotic behavior, so they are in the same group.
The running time of this algorithm is O(1) because the number of functions is fixed and small (12 in this case). The pseudocode simply assigns the functions to groups and prints the groups, which takes constant time regardless of the size of the input.

To sort the following twelve functions by order of growth from slowest to fastest, the following algorithm can be used:Algorithm:Sort functions by order of growth using merge sort method.Merge sort method is used to sort the functions in increasing order. Merge sort is an efficient, comparison-based sorting algorithm that works by dividing an array into two halves, sorting the halves separately, and then merging them together.
The idea behind the merge sort algorithm is to divide an array into two halves, sort each half separately, and then merge the two halves back together. It's a recursive algorithm, and it keeps dividing the array in half until it reaches a single element, which is already sorted.
The algorithm then works its way back up, merging the sorted halves back together into a single sorted array. Pseudocode: MERGE-SORT(A, p, r)1 if p < r2 q = ⌊(p+r)/2⌋3 MERGE-SORT(A, p, q)4 MERGE-SORT(A, q+1, r)5 MERGE(A, p, q, r)The correctness of the algorithm is guaranteed by the fact that merge sort is a well-established and proven algorithm for sorting arrays. It is also a stable algorithm, meaning that it maintains the relative order of equal elements. Thus, it is a reliable and accurate algorithm for sorting functions by order of growth.The running time of merge sort algorithm is O(n log n). The worst-case running time of merge sort is also O(n log n). However, the constant factor is larger than that of quicksort, making it slower in practice than quicksort for small lists. But, for large enough lists, merge sort is often faster than quicksort, because it is more stable and uses fewer comparisons.

Determine the resistance of 3km of copper having a diameter of 0,65mm if the resistivity of copper is 1,7x10^8
Answers
Answer:
Resistance of copper = 1.54 * 10^18 Ohms
Explanation:
Given the following data;
Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m
Resistivity, P = 1.7 * 10^8 Ωm
Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m
\( Radius, r = \frac {diameter}{2} \)
\( Radius = \frac {0.00065}{2} \)
Radius = 0.000325 m
To find the resistance;
Mathematically, resistance is given by the formula;
\( Resistance = P \frac {L}{A} \)
Where;
P is the resistivity of the material. L is the length of the material.A is the cross-sectional area of the material.First of all, we would find the cross-sectional area of copper.
Area of circle = πr²
Substituting into the equation, we have;
Area = 3.142 * (0.000325)²
Area = 3.142 * 1.05625 × 10^-7
Area = 3.32 × 10^-7 m²
Now, to find the resistance of copper;
\( Resistance = 1.7 * 10^{8} \frac {3000}{3.32 * 10^{-7}} \)
\( Resistance = 1.7 * 10^{8} * 903614.46 \)
Resistance = 1.54 * 10^18 Ohms

An electrical engineer at GRIDCO is given two separate toolboxes to keep his working tools. The first toolbox has 4 white fuses and 3 black fuses and the second toolbox has 3 white fuses and 5 black fuses. Suppose the engineer select a fuse from the first toolbox and placed unseen in the second toolbox. What is the probability that: (a) the fuse drawn from the second toolbox is black? (B) the fuse drawn from the second toolbox is white? (8) ane is white?
Answers
(a) The probability of drawing a black fuse from the second toolbox is 4/7.
(b) The probability of drawing a white fuse from the second toolbox is 3/7.
(c) The probability that one fuse is white is 27/49.
To calculate the probabilities, we need to consider the number of white and black fuses in each toolbox.
First, let's determine the total number of fuses in each toolbox:
First Toolbox:
Total fuses = 4 white fuses + 3 black fuses = 7 fuses
Second Toolbox:
Total fuses = 3 white fuses + 5 black fuses = 8 fuses
(a) The probability that the fuse drawn from the second toolbox is black:
The probability of drawing a black fuse from the second toolbox depends on the fuse selected from the first toolbox. There are two scenarios to consider:
Scenario 1: The fuse selected from the first toolbox is black.
In this case, the second toolbox will have 3 black fuses remaining out of the total 7 fuses.
Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)
Probability = 3/7
Scenario 2: The fuse selected from the first toolbox is white.
In this case, the second toolbox will have 5 black fuses out of the total 7 fuses.
Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)
Probability = 5/7
To calculate the overall probability, we need to consider the probability of each scenario and weigh it by the probability of selecting a fuse of that color from the first toolbox. Since the fuse from the first toolbox has an equal chance of being white or black, we need to take an average of the probabilities in both scenarios.
Probability of drawing a black fuse from the second toolbox = (Probability of scenario 1 + Probability of scenario 2)/2
Probability of drawing a black fuse from the second toolbox = (3/7 + 5/7)/2
Probability of drawing a black fuse from the second toolbox = 8/14
Probability of drawing a black fuse from the second toolbox = 4/7
Therefore, the probability of drawing a black fuse from the second toolbox is 4/7.
(b) The probability that the fuse drawn from the second toolbox is white:
Similarly, we can calculate the probability of drawing a white fuse from the second toolbox. It will be the complement of the probability of drawing a black fuse.
Probability of drawing a white fuse from the second toolbox = 1 - Probability of drawing a black fuse from the second toolbox
Probability of drawing a white fuse from the second toolbox = 1 - 4/7
Probability of drawing a white fuse from the second toolbox = 3/7
Therefore, the probability of drawing a white fuse from the second toolbox is 3/7.
(c) The probability that one is white:
To calculate the probability that one fuse is white, we need to consider both scenarios: either the fuse drawn from the first toolbox is white and the fuse drawn from the second toolbox is black, or the fuse drawn from the first toolbox is black and the fuse drawn from the second toolbox is white.
Scenario 1: Fuse drawn from the first toolbox is white, and the second toolbox has a black fuse:
Probability = (Probability of drawing a white fuse from the first toolbox) * (Probability of drawing a black fuse from the second toolbox)
Probability = (3/7) * (5/7)
Scenario 2: Fuse drawn from the first toolbox is black, and the second toolbox has a white fuse:
Probability = (Probability of drawing a black fuse from the first toolbox) * (Probability of drawing a white fuse from the second toolbox)
Probability = (4/7) * (3/7)
To calculate the overall probability, we need to sum up the probabilities of both scenarios:
Probability that one fuse is white = Probability
of scenario 1 + Probability of scenario 2
Probability that one fuse is white = (3/7) * (5/7) + (4/7) * (3/7)
Probability that one fuse is white = 15/49 + 12/49
Probability that one fuse is white = 27/49
Therefore, the probability that one fuse is white is 27/49.

based on these s-n curves, would you expect ductile cast iron to fail under cyclic loading of 200 mpa for 109 cycles?
Answers
Based on these s-n curves, it is difficult to say for certain whether or not ductile cast iron would fail under cyclic loading of 200 MPa for 109 cycles.
The s-n curves provide information on the fatigue strength of a material under different levels of stress and cycles of loading. However, other factors such as the specific composition and microstructure of the ductile cast iron, as well as any potential defects or flaws in the material, can also play a role in determining its fatigue life. Therefore, it would be important to consider additional information and testing data specific to the ductile cast iron in question in order to make a more accurate prediction about its potential failure under cyclic loading of 200 MPa for 109 cycles.
Based on the given S-N curves, ductile cast iron is expected to fail under cyclic loading of 200 MPa for 10^9 cycles.

Based on the given S-N curves, the ductile cast iron fail under cyclic loading of 200 MPa for 10^9 cycles if the curve shows that the stress level of 200 MPa exceeds the endurance limit for ductile cast iron at that specific number of cycles.
To determine this, follow these steps:
1. Locate the S-N curve for ductile cast iron.
2. Find the 10^9 cycles point on the horizontal axis (number of cycles).
3. Trace a vertical line upward from the 10^9 cycles point until it intersects the S-N curve.
4. Read the corresponding stress value on the vertical axis (stress amplitude) at the intersection point.
5. Compare the stress value from the S-N curve to the given cyclic loading of 200 MPa.
If the stress value from the S-N curve is lower than 200 MPa at 10^9 cycles, it indicates that ductile cast iron would likely fail under cyclic loading of 200 MPa for 10^9 cycles. If the stress value is higher than 200 MPa, ductile cast iron is expected to withstand the cyclic loading without failure.

which technique separates proteins independently of their charge
Answers
The technique that separates proteins independently of their charge is called size exclusion chromatography.
This technique separates proteins based on their size and shape, rather than their charge. In size exclusion chromatography, the protein mixture is passed through a column containing beads with pores of a specific size.
Larger proteins are unable to fit into the pores and therefore elute from the column first, while smaller proteins are able to enter the pores and elute later. This allows for the separation of proteins based on their size, with smaller proteins eluting later and larger proteins eluting first.
Size exclusion chromatography is particularly useful for purifying proteins and removing impurities from a sample, as it can separate a wide range of proteins regardless of their charge or other physical properties.
This technique is commonly used in the biotechnology industry for protein purification and analysis, and has been instrumental in the development of many important therapies and biologics.

Find the voltage gain v0/vs of the circuit given below, where R1 = 14 kΩ and R2 = 13 kΩ
Answers
Answer:
The voltage gain is 2.07.
Explanation:
Given that,
Resistance \(R_{1}=14\ k\Omega\)
Resistance \(R_{2}=13\ k\Omega\)
We need to calculate the voltage gain
Using formula of voltage source
\(V_{s}=\dfrac{V_{o}\times R_{2}}{R_{1}+R_{2}}\)
\(\dfrac{V_{o}}{V_{s}}=\dfrac{R_{1}+R_{2}}{R_{2}}\)
Where, \(R_{1}\) = first resistance
\(R_{2}\) =second resistance
\(V_{s}\) = source voltage
\(V_{o}\) = output voltage
Put the value into the formula
\(\dfrac{V_{o}}{V_{s}}=\dfrac{14+13}{13}\)
\(\dfrac{V_{o}}{V_{s}}=2.07\)
Hence, The voltage gain is 2.07
