The length of the hypotenuse will be 33.55 feet in the given triangle.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The triangle given in the question is a right triangle.

In a triangle side A has a length of 18.5 ft and side B has a length of 28 ft

A right triangle is represented as a triangle in which one angle is a right angle or two sides are perpendicular.

To determine the length of the hypotenuse.

According to Pythagoras's theorem,

a² + b² = c²

Here a = 18.5 and b = 28

The length of the hypotenuse is c.

(18.5)² + (28)² =  c²

342.25 + 784 = c²

c² = 1126.25

c = 33.55

Therefore, the length of the hypotenuse will be 33.55 feet.

If we tried to further accelerate a Supersonic fluid with a diverging diffuser,  the pressure will decrease due to an increase in area. This can be described as :

dA/A = dP/ρV² (1-M²) for supersonic flow Mach Number, M: M > 11 - M² < 0 (dA/A) = -K (dP/ρV²)k = 1-M²

Supersonic flow fields have Mach numbers greater than one at every location. Supersonic flows are usually characterized by the presence of shock waves, which cause abrupt changes in flow characteristics and streamlines (in contrast to the smooth, continuous variations in subsonic flows).

Supersonic and subsonic relate to speeds that are faster or slower than the speed of sound, respectively. Supersonic means traveling faster than the speed of sound, which is 343.2 m/s (1,126 ft/s). Subsonic speeds are defined as anything moving slower than the speed of sound.

Explanation:

Just like in the steel mills with the big furnaces that's what causes all the smoke to come out of the stacks

Answer:

d is correct

Explanation:

Answer:

a) efficiency is equal to 67.2%, and this is lesser than the maximum obtainable efficiency, so this power output is possible.

b) efficiency is 75%, this is approximately equal to the maximum obtainable efficiency, but not more that it. This power output is also possible.

Explanation:

Cold reservoir temperature Tc = 295 K

Hot reservoir temperature Th = 1175 K

Energy input Q = 150000 K/h

Converting to kJ/s, Q  = 150000/3600 = 41.66 kJ/s

Maximum efficiency that can be obtained from this cycle = \(1 - \frac{Tc}{Th}\)

==> \(1 - \frac{295}{1175}\) = 0.748 ≅ 75%

also recall that actual cycle efficiency = \(\frac{W}{Q}\)

Where W is the energy output or work

a) for work of 28 kW,

eff =  \(\frac{W}{Q}\) =  \(\frac{28}{41.66}\) = 0.672 ≅ 67.2%

this is lesser than the maximum obtainable efficiency, so this power output is possible.

b) for work of 31.2 kW

eff =  \(\frac{W}{Q}\) =  \(\frac{31.2}{41.66}\) = 0.748 ≅ 75%

this is approximately equal to the maximum obtainable efficiency, but not more that it. This power output is possible.

A  faulty starter motor can be identified through a starter current draw test by observing high or low current draw, inconsistent results, or no current draw at all. When conducting a starter current draw test, the goal is to determine if the starter motor is functioning properly.

Always compare the results to the manufacturer's specifications to determine if the starter motor is operating within acceptable parameters.

To evaluate this, you'll need to take into account the current draw and compare it to the manufacturer's specifications. A faulty starter motor can be indicated by one of the following results:

1. High current draw: If the current draw is significantly higher than the specified value provided by the manufacturer, it may indicate that the starter motor is faulty. This excessive current draw can be due to internal shorts, a damaged armature, or worn brushes.

2. Low current draw: Conversely, a low current draw may also indicate a problem with the starter motor. This can be caused by poor electrical connections, a faulty solenoid, or an open winding in the armature.

3. Inconsistent results: If the starter current draw test produces inconsistent results, such as fluctuating current draw values or intermittent functionality, the starter motor may be faulty. This could be due to loose connections, worn components, or other internal issues.

4. No current draw: If there is no current draw at all during the test, the starter motor is likely faulty or has completely failed. This may be due to a broken winding, a short circuit, or a failed solenoid.

The force sensor would read low. When there is an angle ϴ between the direction the string pulls and the sensor's measuring direction.

the measured force is the component of the force vector in the sensor's direction. As ϴ increases, the component of the force vector in the sensor's direction decreases, resulting in a lower reading on the force sensor. The force sensor measures the force along its measuring direction, so any deviation from that direction reduces the measured force value. The force sensor would read low. When there is an angle ϴ between the direction the string pulls and the sensor's measuring direction, the measured force would be lower due to the reduction in the component of the force vector along the sensor's measuring direction.

To determine whether you should increase or decrease the length of the pendulum of your grandfather clock, you need to understand the relationship between pendulum length and time period.

The time period of a pendulum is the time it takes for one complete oscillation (back and forth). It can be calculated using the formula:

T = 2π√(L/g)

Where:

T is the time period,

L is the length of the pendulum, and

g is the acceleration due to gravity.

If the clock gains 21 seconds per day, it means that the time period is longer than the desired value. To decrease the time period, you need to decrease the pendulum length.

To find out by how much you should change the pendulum length, you can use the following steps:

Calculate the current time period (T) using the given length (L = 0.9930 m) and the known acceleration due to gravity (g = 9.8 m/s^2).

Determine the desired time period based on the clock's accuracy (24 hours = 86400 seconds).

Find the difference between the current time period and the desired time period.

Adjust the pendulum length in the appropriate direction (decrease in this case) to reduce the time period difference.

Convert the difference in length to millimeters (mm) for precision.

By performing these calculations, you can determine the specific amount by which you should decrease the pendulum length in millimeters.

The formula to calculate the terminal voltage of a synchronous generator is given by Vt = E + Ia (RcosΦ + XsinΦ), where Vt is the terminal voltage, E is the generated voltage, Ia is the armature current, R is the stator resistance per phase, Φ is the power factor angle, and X is the stator reactance per phase.

In this case, we are given the line voltage (VL) as 11 kV, apparent power (S) as 2000 KVA, power factor (pf) as 0.8 lagging, stator resistance (R) as 0.3 Ω, and stator reactance (X) as 5 Ω.

To calculate the terminal voltage (Vt) for a load current at 0.8 leading power factor, we need to calculate the armature current (Ia) first using the given apparent power and power factor. The armature current is calculated as Ia = S / (VL * pf), which gives us 215.05 A (rms) in this case.

Next, we substitute the given values in the formula Vt = E + Ia (RcosΦ + XsinΦ). As the generator is operating at rated voltage and no armature reaction, generated voltage (E) is equal to line voltage (VL), which is 11 kV. Substituting the values and calculating, we get the terminal voltage (Vt) as 10,317.3 V. Therefore, the terminal voltage of the synchronous generator under the same excitation and with the same load current at 0.8 power factor leading is 10,317.3 V (rounded to one decimal place).

Explanation:

Alternative C has the highest Incremental Benefit/Cost Ratio, followed by Alternative B, making them more preferable than Alternative A.

To compare the three alternatives (A, B, and C) using the Incremental Benefit/Cost Ratio method at a discount rate of 4% per year, we need to calculate the present value of costs, present value of benefits, and incremental benefit/cost ratio for each alternative.

Step 1: Calculate the present value of costs and benefits for each alternative.

For Alternative A:

- Construction Cost: $250,000

- Benefits per year: $320,000

- Service Life: 7 years

Using the formula for present value, we can calculate the present value of costs and benefits for Alternative A:

Present Value of Costs (PV A) = Construction Cost / (1 + discount rate)^service life = $250,000 / (1 + 0.04)^7 ≈ $186,065.69

Present Value of Benefits (PV A) = Benefits per year * (1 - (1 + discount rate)^-service life) / discount rate = $320,000 * (1 - (1 + 0.04)^-7) / 0.04 ≈ $1,883,076.14

For Alternative B and C, follow the same steps to calculate their respective present value of costs and benefits:

Alternative B:

- Construction Cost: $400,000

- Benefits per year: $370,000

- Service Life: 15 years

PV B (Cost) ≈ $267,507.55

PV B (Benefits) ≈ $3,048,852.53

Alternative C:

- Construction Cost: $700,000

- Benefits per year: $380,000

- Service Life: 25 years

PV C (Cost) ≈ $395,661.79

PV C (Benefits) ≈ $6,750,228.83

Step 2: Calculate the incremental benefit and incremental cost between each alternative and the previous one.

Incremental Benefit (IB) = Present Value of Benefits (Current Alternative) - Present Value of Benefits (Previous Alternative)

Incremental Cost (IC) = Present Value of Costs (Current Alternative) - Present Value of Costs (Previous Alternative)

IB_AB = PV B (Benefits) - PV A (Benefits) ≈ $3,048,852.53 - $1,883,076.14 ≈ $1,165,776.39

IC_AB = PV B (Cost) - PV A (Cost) ≈ $267,507.55 - $186,065.69 ≈ $81,441.86

IB_BC = PV C (Benefits) - PV B (Benefits) ≈ $6,750,228.83 - $3,048,852.53 ≈ $3,701,376.30

IC_BC = PV C (Cost) - PV B (Cost) ≈ $395,661.79 - $267,507.55 ≈ $128,154.24

Step 3: Calculate the Incremental Benefit/Cost Ratio (IB/IC) for each alternative.

IB/IC ratio = Incremental Benefit / Incremental Cost

IB/IC_AB = $1,165,776.39 / $81,441.86 ≈ 14.31

IB/IC_BC = $3,701,376.30 / $128,154.24 ≈ 28.91

Step 4: Compare the Incremental Benefit/Cost Ratios.

Since IB/IC_AB is less than IB/IC_BC, we can conclude that Alternative B is preferred over Alternative A, and Alternative C is preferred over Alternative B.

In summary, based on the Incremental Benefit/Cost Ratio method at a 4% discount rate per year, the

ranking of the alternatives from most preferred to least preferred is:

1. Alternative C

2. Alternative B

3. Alternative A

The continuity equation allows finding the results for the speed and flow of the outlet pipe are:

Fluid mechanics studies the movement and fluid dynamics, it is described  by two fundamental relationships:

          \(P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2\)  

Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.

            \(A_1v_1 = A_2 v_2\)

Where A₁ and A₂ is the area of ​​the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet

They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity

         \(v_2 = ( \frac{A_1}{A_2} )^2 \ v_1\)  

the cross section of the tavern is

        A = \(\pi r^2 = \pi \ d^2/4\)  

Where r is the radius and d is the diameter

Let's substitutes

        \(v_2 = (\frac{d_1}{d_2} )^2 \ v_1\)  

        \(v_2 = (\frac{0.02}{0.1} )^2 \ 10\)  

        v₂ = 0.4 m / s

The flow  (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore

        Q = A v

        Q = \(\pi \frac{d_2^2}{4} \ v_2\)π d2 ^ 2 v2

        Q = \(\pi \ \frac{0.1^2}{4} \ 0.4\)

        Q = 3.14 10⁻³ m ^ 3 / s

As the transported liquid is water

         1 liter water = 1 kg

Consequently

         1 m³ = 1000 liter = 1000 kg of water

Let's reduce the flow

         Q = 3.14 10⁻³ m³/s ( \(\frac{10^3 kg}{1 m^3}\) )

         Q = 3.14 kg / s
