forty gal/min of a hydrocarbon fuel having a spesific gravity of 0.91 flow into a tank truck with load limit of 40,000 lb of fuel. How long will it takee to fill the tank in the truck?
Answer: 131.75minutes
Explanation:
First if all, we've to find the density of liquid which will be:
= Specific gravity × Density to pure water
= 0.91 × 8.34lb/gallon
= 7.59lb/gallon
Then, the volume that's required to fill the tank will be:
= Load limit/Density of fluid
= 40000/7.59
= 5270.1gallon
Now, the time taken will be:
= V/F
= 5270.1/40
= 131.75min
It'll take 131.75 minutes to fill the tank in the truck.

Rx is the individual resistor across which the output voltage drop is being measured, and VRx is the voltage divider formula for a circuit with many resistors.
The distribution of the input voltage among the divider's parts produces voltage division. Two resistors linked in series with the input voltage applied across them and the output voltage emerging from the connection between them serve as a straightforward example of a voltage divider. The currents flowing through the resistors R1 and R2 are I1 and I2, respectively, while the voltage across each element is VS. At node P, the KCL equation will be. IS=I1+I2.

Explanation:
Convert to an equation for example P%* X=Y
P is 7.5% X is 140, so the equation Is 7.5 percent * 14= Y
convert 7.5% Into a decimal by removing the percent sign and deviding by 7.5/100= 0.075
Substitute 0.075 for 7.5% in the equation: 7.5%*140=Y becomes 0.075*140= 10.5
In 1984, General Motors (GM) and Toyota opened NUMMI as a joint venture in California. The venture was
dissolved and the NUMMI plant was finally closed after GM declared bankruptcy in 2009. After listening to the Podcast NUMMI Case Study (approx 60 min), write essay regarding causes of GM's failure to introduce the lessons learnt from the NUMMI venture across other factories in the GM network. The report should be focused onthe examination and analysis of the specific issues presented in the case study/podcast.
GM's failure to introduce the lessons learned from the NUMMI venture across other factories in the GM network can be attributed to several key factors presented in the case study/podcast. These factors include:
Resistance to change: GM's corporate culture and long-established practices made it difficult for the company to embrace the new production methods and employee empowerment strategies implemented at NUMMI. The hierarchical structure and lack of open communication within GM hindered the dissemination of knowledge and best practices across other factories.
Lack of leadership alignment: The case study highlights how the top leadership at GM was not fully aligned with the principles and practices implemented at NUMMI. Without strong support and commitment from top management, it was challenging to drive the necessary changes and replicate the success of the joint venture.
Inadequate training and education: The NUMMI venture emphasized the importance of training and developing employees to build a skilled and engaged workforce. However, GM failed to invest in similar training programs and employee development initiatives across its other factories. This lack of investment in human capital resulted in a workforce that was resistant to change and unable to fully adopt the NUMMI principles.
Resistance from labor unions: The case study points out that the UAW, the main labor union representing GM workers, was skeptical of the NUMMI venture and resistant to some of the changes proposed. This resistance made it difficult for GM to implement the lessons learned from NUMMI across its unionized factories.
GM's failure to introduce the lessons learned from the NUMMI venture can be attributed to resistance to change, lack of leadership alignment, inadequate training and education, and resistance from labor unions. Overcoming these challenges would have required a fundamental shift in GM's culture, stronger leadership support, investment in training and education, and collaborative efforts with labor unions.

A hydrogenation catalyst is prepared by soaking alumina particles (100-150 mesh size) in aqueous NiNO3 solution. After drying and reduction, the particles contain about 7 wt% NiO. This catalyst is then made into large cylindrical pellets for rate studies. The gross measurements for one pellet are: Mass, g 3.15 Diameter, mm 25 Thickness, mm 6 Volume, cm3 3.22 The alumina particles contain micropores, and the pelleting process introduces macropores surrounding the particles. If the macropore volume of the pellet is 0.645 cm3 and the micropore volume is 0.40 cm3 /g of particles, determine: i] The density of the pellet ii] The macropore volume in cm3 /g iii] The macropore void fraction in the pellet iv] The micropore void fraction in the pellet v] The solid fraction vi] The density of the particles
i] The density of the pellet is 0.977 g/cm^{3}. ii] The macropore volume in cm^{3}/g is 0.205 cm^{3}/g. iii] The macropore void fraction in the pellet is 25.1%.iv] The micropore void fraction in the pellet is 49.0%. v] The solid fraction of the pellet is 25.9%. vi] The density of the particles is 1.222 g/cm^{3}.
i] To determine the density of the pellet, we can use the formula:
Density = Mass / Volume
Given that the mass of the pellet is 3.15 g and the volume is 3.22cm^{3}, we can calculate the density as follows:
Density = 3.15 g / 3.22 cm^{3}≈ 0.977 \(g/cm^{3\)
ii] The macropore volume in cm3/g can be calculated by dividing the macropore volume of the pellet (0.645 cm3) by the mass of the pellet (3.15 g):
Macropore volume = 0.645 cm^{3} / 3.15 g ≈ 0.205 \(cm^{3} /g\)
iii] The macropore void fraction in the pellet can be calculated using the formula:
Macropore void fraction = Macropore volume / Total volume of the pellet
Total volume of the pellet = Volume - Macropore volume = 3.22 cm^{3}- 0.645 cm^{3} = 2.575 cm^{3}
Macropore void fraction = 0.645 cm^{3} / 2.575 \(cm^{3}\)≈ 0.251 or 25.1%
iv] The micropore void fraction in the pellet can be calculated using the given micropore volume of the particles (0.40 cm^{3} /g) and the mass of the pellet (3.15 g):
Micropore volume in the pellet = Micropore volume/g x Mass
Micropore volume in the pellet = 0.40 \(cm^{3} /g\) x 3.15 g = 1.26 cm3
Micropore void fraction = Micropore volume in the pellet / Total volume of the pellet
Micropore void fraction = 1.26 \(cm^{3}\) / 2.575 \(cm^{3}\) ≈ 0.490 or 49.0%
v] The solid fraction of the pellet can be calculated by subtracting the sum of macropore and micropore void fractions from 1:
Solid fraction = 1 - (Macropore void fraction + Micropore void fraction)
Solid fraction = 1 - (0.251 + 0.490) ≈ 0.259 or 25.9%
vi] The density of the particles can be determined using the mass of the pellet (3.15 g) and the total volume of the particles:
Total volume of the particles = Volume - Macropore volume = 3.22 \(cm^{3}\)- 0.645 \(cm^{3}\) = 2.575\(cm^{3}\)
Density of the particles = Mass / Total volume of the particles
Density of the particles = 3.15 g / 2.575\(cm^{3}\) ≈ 1.222 \(g/cm^{3}\)

The maximum dry density in lb/ft3 is most nearly:_______
Answer:
115 Ib/ft^3
Explanation:
To determine the maximum dry density in Ib/ft3 we have to calculate :
Bulk unit weight ( yb ) ; W / v
Dry unit weight ( yd. ) : yb / ( 1 + w )
For every set of data given
assuming v = 1/30 ft^3
calculating for the 3 data set ( maximum dry density )
weight of soil (W) = 4.40
moisture content (%) (w) = 15.0 = 0.15
Bulk unit weight (yb) = 4.40 / (1/30) = 132 Ib/ft^3
Dry unit weight ( yd. ) = 132 / ( 1 + 0.15 ) = 114.702 Ib/ft^3
therefore after calculations the maximum dry density in Ib/ft^3 ≈ 115 Ib/ft^3

The processing of characters on a monitor typically involves the rendering of pixels based on the input data. Once the rendering process is completed, the monitor may update the screen accordingly. However, this process does not automatically trigger a change in the DSR signal. The DSR signal depends on the specific hardware and communication protocol being used and is typically controlled by the transmitting or receiving device, not the monitor itself.

Water flows steadily through the pipe as shown below, such that the pressure at section (1) and at section (2) are 300 kPa and 100 kPa respectively. Determine the diameter of the pipe at section (2), D, if the velocity at section (1) is 20 m/sec and viscous effects are negligible.
Answer:
The velocity at section is approximately 42.2 m/s
Explanation:
For the water flowing through the pipe, we have;
The pressure at section (1), P₁ = 300 kPa
The pressure at section (2), P₂ = 100 kPa
The diameter at section (1), D₁ = 0.1 m
The height of section (1) above section (2), D₂ = 50 m
The velocity at section (1), v₁ = 20 m/s
Let 'v₂' represent the velocity at section (2)
According to Bernoulli's equation, we have;
\(z_1 + \dfrac{P_1}{\rho \cdot g} + \dfrac{v^2_1}{2 \cdot g} = z_2 + \dfrac{P_2}{\rho \cdot g} + \dfrac{v^2_2}{2 \cdot g}\)
Where;
ρ = The density of water = 997 kg/m³
g = The acceleration due to gravity = 9.8 m/s²
z₁ = 50 m
z₂ = The reference = 0 m
By plugging in the values, we have;
\(50 \, m + \dfrac{300 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{(20 \, m/s)^2}{2 \times 9.8 \, m/s^2} = \dfrac{100 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)50 m + 30.704358 m + 20.4081633 m = 10.234786 m + \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)
50 m + 30.704358 m + 20.4081633 m - 10.234786 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)
90.8777353 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)
v₂² = 2 × 9.8 m/s² × 90.8777353 m
v₂² = 1,781.20361 m²/s²
