Explanation:

Its line length must be converted into wavelengths for the Smith chart to be used.

\(\to \beta = \frac{2 \pi }{\lambda } \\\\\to u_p = \frac{\omega }{\beta}\\\\\lambda =\frac{2 pi}{\beta} =\frac{2 \pi U_p}{\omega}=\frac{c}{\sqrt{\varepsilon_r f}}\)

                        \(= \frac{3 \times 10^8}{ 2.25 \times (5 \times 10^9)}\\\\= \frac{3}{ 2.25 \times 5\times 10 }\\\\= \frac{3}{ 22.5 \times 5 }\\\\= \frac{3}{ 112.5}\\\\= 0.04 \ m.\)

\(l =\frac{0.30 }{0.04 } \times \lambda\)

  \(= 7.5 \lambda\)

Because it is an integrated half-wavelength amount,

\(Z_{in} = Z_L = 150 \ \Omega\)

The thermal conductivities in the ξ and η directions, kξ and kη, are known for a flat plate of laminated material with laminations making an angle β with the surfaces. To determine the overall thermal conductivity of the plate, we need to consider the effective thermal conductivity in the direction of heat flow. This can be calculated using the rule of mixtures.

The effective thermal conductivity, keff, is given by the equation:

keff = (kξ cos²β + kη sin²β)

Here, cos²β represents the fraction of heat flow in the direction of kξ, and sin²β represents the fraction of heat flow in the direction of kη. By substituting the given values of kξ, kη, and β into the equation, you can calculate the effective thermal conductivity of the laminated plate.

Remember that this calculation assumes that heat flow is one-dimensional and perpendicular to the surfaces. Additionally, it is important to note that this equation applies only to flat plates of laminated material and may not be applicable to other geometries or materials.

To minimize the mean while keeping the boxplot unchanged, the points should be moved closer to the lower extreme. reducing the overall average and making the mean as small as possible. However, it's important to note that this may affect the quartiles and extreme values, as they are determined by the distribution of the data.

To move points so that the boxplot is unchanged but the mean is as small as possible, you would have to move the points closer to the lower extreme. A box plot, also known as a box and whisker plot, is a graph that depicts a dataset's variability and distribution by dividing the data into quartiles. The box's center line represents the median, the top and bottom lines represent the upper and lower quartiles, and the whiskers extend to the most extreme data points. When the boxplot is unchanged, the quartiles, median, and extreme values do not shift from their original position. On the other hand, the mean is the average of a dataset, obtained by adding up all the values and dividing by the number of values. To make the mean as small as possible, you must bring the data closer to the smallest values. Therefore, moving points towards the lower extreme of the boxplot will accomplish this. reducing the overall average and making the mean as small as possible.

Answer:

Heat is lost at the rate of 750 J/s or W

The thermal resistance is 1 K/W

Explanation:

interior temperature \(T_{2}\) = 900 °C

wall thickness t = 60 cm = 0.6 m

width = 1 m

breadth = 1.5 m

thermal conductivity k = 0.4 W/m-K

outside temperature \(T_{1}\) = 150 °C

heat through the wall = ?

The area of the wall A = w x b = 1 x 1.5 = 1.5 m^2

Temperature difference \(dt\) = \(T_{2}\) - \(T_{1}\) = 900 - 150 = 750 °C

note that \(dt\) is also equal to 750 K since to convert from °C to K we'll have to add 273 to both temperature, which will still cancel out when we subtract the two temperatures.

To get the heat that escapes through the wall, we use the equation

Q = Ak\(\frac{dt}{t}\)

substituting values, we have

Q = 1.5 x 0.4 x \(\frac{750}{0.6}\) = 750 J/s or W

Thermal resistance \(R_{t}\) = \(\frac{dt}{Q}\)

\(R_{t}\) = 750/750 = 1 K/W

Explanation:

By defining the truth table,writing Boolean expressions, Implementing the PAL and PAL equations we can Design a 3-Bit comparetor to compare a level of 100 Using PAL.

To design a 3-bit comparator using PAL (Programmable Array Logic), we can follow these steps:

Step 1: Define the truth table:

We need to compare a level of 100 with a 3-bit input. The truth table for the comparator is as follows:

```A2 A1 A0 | X2 X1 X0

-------------------

0  0  0  | 0  0  0

0  0  1  | 0  0  1

0  1  0  | 0  1  1

0  1  1  | 0  1  1

1  0  0  | 1  0  0

1  0  1  | 1  0  0

1  1  0  | 1  0  0

1  1  1  | 1  1  0

```Step 2: Write the Boolean expressions for the output bits (X2, X1, X0):

Based on the truth table, we can write the Boolean expressions for the output bits:

```X2 = A2'

X1 = (A2 A1')' = A2 + A1

X0 = (A2' A1' A0)' = A2 + A1 + A0

```Step 3: Implementing the PAL:

Now, we can use a PAL to implement the comparator using the Boolean expressions derived above. PALs typically consist of an AND array and an OR array.

The AND array will have the inputs A2, A1, and A0 connected to the product terms. The OR array will have the outputs X2, X1, and X0 connected to the sum terms.

The connections for the PAL are as follows:

```Inputs:

---------

A2 -> Product term 1

A1 -> Product term 2

A0 -> Product term 3

Outputs:

---------

X2 -> Sum term 1

X1 -> Sum term 2

X0 -> Sum term 3

```Step 4: Implementing the PAL equations:

Using the connections described above, we can implement the PAL equations:

```Product term 1: A2'

Product term 2: A2 + A1

Product term 3: A2 + A1 + A0

Sum term 1: X2

Sum term 2: X1

Sum term 3: X0

```The above connections and equations represent a 3-bit comparator using a PAL to compare a level of 100.

Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

A 60Hz, 0.5-HP single-phase motor in a washing machine (120V RMS) has an efficiency of 78% at full load (rated output power) and a power factor of 0.72 lagging.

To find the line current, first determine the real power (P) using the formula P = HP × 746, where HP is 0.5. This gives P = 373W. Since efficiency is 78%, the input power (Pin) is P/0.78 = 478.21W. Now, use the power factor (0.72) to find the apparent power (S) by dividing Pin by the power factor: S = 478.21/0.72 = 664.18 VA. To find the line current (I), divide the apparent power (S) by the voltage (120V): I = 664.18/120 = 5.53 A.
The reactive power (Q) can be found using the formula Q = S × sin(arccos(0.72)), resulting in Q = 664.18 × sin(arccos(0.72)) = 536.65 VAR. In summary, the line current is 5.53 A, the reactive power is 536.65 VAR, and the apparent power is 664.18 VA.

The channel section's center of gravity, measured from the rear of the web, is 80 mm.

To find the center of gravity of the channel section, break it down into simpler shapes and use the principle of moments.

First, consider the rectangle formed by the back of the web and the thickness of the flanges (300 mm x 20 mm x 10 mm).

Next, consider the two rectangles formed by the flanges (300 mm x 10 mm x 10 mm).

Finally, take into account the position of the web itself.

The web is centered within the thickness of the flanges, so its center of gravity is at a distance of 10 mm / 2 = 5 mm from the back of the web.

The area of the large rectangle is 300 mm x 20 mm = 6000 mm², and the areas of the two smaller rectangles are each 300 mm x 10 mm = 3000 mm².

So the overall area of the channel section is 6000 mm² + 2 x 3000 mm² = 12000 mm².

The weighted average distance from the back of the web is then:

(6000 mm² x 5 mm) + (3000 mm² x 5 mm) + (3000 mm² x 155 mm) / 12000 mm² = 80 mm

Therefore, the center of gravity of the channel section from the back of the web is 80 mm.

Mooring and bottom tracking are two widely used methods to measure ocean currents. Although both methods have their advantages and disadvantages, mooring offers more advantages than bottom tracking.

A mooring is a stationary instrument array that is anchored to the seafloor and is used to track current speed, direction, temperature, salinity, and other oceanographic parameters over time. It contains a string of instruments that are installed at various depths, with each instrument measuring different oceanographic parameters. The mooring array transmits data to a surface buoy, which relays it to a shore station via satellite or radio.

The mooring is retrieved after a set time, and the data is analyzed. The speed and direction of the current can be determined by analyzing the data. This method is useful in measuring the surface and near-surface. Bottom tracking is not useful in areas where ships cannot go. Bottom tracking does not provide a long-term record of current speed, direction, and other parameters.

Hydroelectric plant turbine selection.

Based on the provided data, we can use the following steps to determine the type of turbines, specific speed, and size of the turbines, as well as the location of the centerline of the turbine with respect to the water level and check for cavitation using Thoma's criteria.

Step 1: Determine the flow rate

The flow rate can be calculated using the formula:

Q = P / (ρgh)

where Q is the flow rate, P is the installed capacity (60 MW), ρ is the density of water (1000 kg/m³), g is the acceleration due to gravity (9.81 m/s²), and h is the net head (20 m).

Plugging in the values, we get:

Q = 60,000,000 / (1000 x 9.81 x 20) = 306.1 m³/s

Step 2: Determine the specific speed

The specific speed (Ns) can be calculated using the formula:

Ns = (n √Q) / (H)^(3/4)

where n is the rotational speed (in revolutions per minute), Q is the flow rate (in cubic meters per second), and H is the net head (in meters).

Plugging in the values, we get:

Ns = (750 x √306.1) / (20)^(3/4) = 64.5

Step 3: Determine the type of turbine

Based on the specific speed, we can determine the type of turbine using the following classification:

Francis turbine: Ns = 10 to 100

Propeller turbine: Ns = 100 to 1,000

Kaplan turbine: Ns = 1,000 to 10,000

Pelton turbine: Ns = 10,000 to 100,000

Since the specific speed falls in the range of 10 to 100, a Francis turbine is suitable for this application.

Step 4: Determine the size of the turbine

The size of the turbine can be determined based on the flow rate and the specific speed. The Francis turbine can be designed to have an efficiency of around 90%, based on the provided draft tube efficiency. Therefore, the power output can be calculated as:

Pout = η x Pin

where Pout is the power output, η is the efficiency (0.9), and Pin is the power input (60 MW).

Plugging in the values, we get:

Pout = 0.9 x 60,000,000 = 54,000,000 W

The power output can also be calculated as:

Pout = ρQgHη

where ρ is the density of water (1000 kg/m³), Q is the flow rate (306.1 m³/s), g is the acceleration due to gravity (9.81 m/s²), H is the net head (20 m), and η is the efficiency (0.9).

Plugging in the values, we get:

Pout = 1000 x 306.1 x 9.81 x 20 x 0.9 = 54,000,000 W

The size of each turbine can be calculated as follows:

Pout = ωT x (π/30) x D^2 x L x ρ/4

where ωT is the angular velocity of the turbine, D is the diameter of the turbine, L is the length of the turbine, and ρ is the density of water.

We can assume a specific speed of 65 for the Francis turbine and use empirical equations to determine the diameter and length of the turbine. For a specific speed of 65, the diameter and length

Answer is 3.2 Ω (Ohms)

Explanation:

From Ohms Law I = V/R

R = V(I)

R = 8(0.4)

R = 3.2

The resistance of a lamp if the current through it is 0.4 A and the voltage across it is 8 V is 3.2 ohm.

According to Ohm's law, when all other physical parameters, including temperature, are held constant, the voltage across a conductor is directly proportional to the current flowing through it.

According to Ohm's Law, the electrical current I flowing through a particular conductor is precisely proportional to the potential difference (voltage) V across its ends (assuming that the conductor's physical properties, such as its temperature and pressure, stay constant). where R is a proportionality constant.

Given:

Current, I= 0.4 A

Voltage, V= 8 V

Using Ohm's Law

V= IR

I = V/R

R = V(I)

R = 8(0.4)

R = 3.2 ohm

Hence, the resistance of a lamp if the current through it is 0.4 A and the voltage across it is 8 V is 3.2 ohm.
