In a transverse wave, the distance between two adjacent crests is equal to the distance between two adjacent troughs.

What is transverse wave?

A transverse wave is a type of wave that moves perpendicular to the direction of the wave. This is in contrast to a longitudinal wave, which moves parallel to the direction of the wave.

An example of a transverse wave is a wave in a rope. When a rope is shaken from side to side, the wave travels along the rope, but the displacement of the rope is perpendicular to the direction of the wave.

Another example of a transverse wave is a light wave, which consists of oscillating electric and magnetic fields that are perpendicular to the direction of the wave's propagation.

The power that the engine will deliver at 3500 rpm is; 87.61 kJ/s

We are given;

Compression Ratio; V₁/V₂ = 22

Cut off ratio; V₃/V₂ = 1.8

Speed; N = 3500 rpm

The temperature after the compression is given by the formula;

T₂ = T₁(V₁/V₂)^(λ - 1)

Where;

T₁ is the temperature before compression

V₁ is the volume before compression

V₂ is the volume after compression

λ is the adiabatic constant of air = 1.4

We are given;

T₁  = 70°C = 70 + 273 = 343 K

Thus;

T₂ = T₁(22)^(1.4 - 1)

T₂ = 1181.03 K

The temperature after the constant pressure expansion in diesel cycle is given by the formula;

T₃/T₂ = V₃/V₂

Plugging in the relevant values;

T₃ = 1181.03 * 1.8

T₃ = 2125.854 K

The temperature T₄ after the isentropic expansion of air is given by the formula;

T₄ = T₃(V₃/V₄)^(λ - 1)

Plugging in the relevant values gives;

T₄ = T₃(1.8V₂/V₄)^(λ - 1)

where V₂/V₄ = V₂/V₁

Thus;

T₄ = T₃(1.8V₂/V₁)^(λ - 1)

T₄ = 2125.854(1.8/22)^(1.4 - 1)

T₄ = 781 K

The mass of air in the system is given by;

m = P₁V₁/RT₁

Where P₁ = 97 KPa and R is gas constant =  0.287kPa⋅m³/kg⋅K

Plugging other relevant values and solving gives;

m = 0.00236 kg

The ideal the specific heat of air at constant pressure cp using ideal gas properties table and by interpolation here is cp = 1.0076 kJ/kg.K

The  heat added to the cycle is given by the formula;

Q_in = mcp(T₃ - T₂)

Plugging the relevant values and solving gives;

Q_in = 2.246 kJ

The heat rejected by the cycle is given by the formula;

Q_out = mcv(T₄ - T₁)

cv is the specific heat at constant volume and from ideal gas properties table and by interpolation gives cv = 0.7205 kJ/kg.K

Thus;

Q_out = 0.00236 * 0.7205(781 - 343)

Q_out = 0.744 KJ

Thus, power that the engine will deliver at 3500 rpm is;

W' = N(Q_in - Q_out)

Where N = 3500 rpm = 3500/60 rps

Thus;

W' = (3500/60)(2.246 - 0.744)

W' = 87.61 kJ/s

The speed adjust by route function of propilot assists with navi-link automatically reducing vehicle speed ensuring a safe and comfortable driving experience for the driver and passengers.

The Speed Adjust by Route function of ProPILOT Assist with Navi-Link can automatically reduce the vehicle speed in several situations. Firstly, when the system detects a sharp turn or curve in the road, it will slow down the car to navigate the turn safely. Secondly, when approaching a highway exit, the system will automatically reduce the speed to smoothly transition to the off-ramp. Thirdly, when approaching a toll booth or a border checkpoint, the system will slow down to ensure a smooth stop at the checkpoint.

Additionally, the Speed Adjust by Route function can also reduce vehicle speed when approaching a construction zone or a roadwork site, where reduced speed limits are often in place. The system will automatically detect the reduced speed limit signs and slow down the car accordingly.

Furthermore, the system can also adjust the speed based on traffic conditions. If the car is following another vehicle too closely, the system will automatically slow down to maintain a safe following distance. Similarly, if traffic is congested or slowed down ahead, the system will slow down the car to avoid collisions and ensure a safe driving experience.

Answer: the cancer risk for an adult male drinking the water for 10 years is 2.88 × 10⁻⁶

Explanation:

firstly, we find the time t required to travel for the contaminant to the well;

Given that, contamination flowing rate = 0.5 ft/day

Distance of well from the site = 1 mile =  5280 ft

so t = 5280 / 0.5 = 10560 days

k is given as 1.94 x 10⁻⁴ 1/day

next we find the Pollutant concentration Ct in the well

Ct = C₀ × e^-( 1.94 x 10⁻⁴ × 10560)

Ct = 0.3 x e^-(kt)  

Ct= 0.0386 mg/L

next we determine the chronic daily intake, CDI

CDI =  (C x CR x EF x ED) / (BW x AT)

where C is average concentration of the contaminant(0.0368mg/L), CR is contact rate (2L/day), EF is exposure frequency (350days/Year), ED is exposure duration (10 years), BW is average body weight (70kg).

now we substitute  

CDI = (0.0368 x 2 x 350 x 10) / ((70x 365) x 70)

= 257.7 / 1788500

= 0.000144 mg/Kg.day

CDI = 1.44 x 10⁻⁴ mg/kg.day  

Finally we calculate the cancer risk, R

Slope factor SF is given as 0.02 Kg.day/mg

Risk, R = I x SF

= 1.44 x 10⁻⁴ mg/kg.day  x 0.02Kg.day/mg    

R = 2.88 × 10⁻⁶

therefore the cancer risk for an adult male drinking the water for 10 years is 2.88 × 10⁻⁶

Starting in 2019, the leak rate threshold for commercial refrigeration equipment with a full charge of 50 or more pounds of an HCFC refrigerant is 30%. This means that if the equipment leaks 30% or more of its total charge in a year, it is considered to be leaking and must be repaired.

This new leak rate threshold was established by the U.S. Environmental Protection Agency (EPA) under the Clean Air Act's Section 608, which sets standards for the handling of refrigerants. The EPA's goal is to reduce the emission of ozone-depleting substances, including HCFC refrigerants, which contribute to climate change and harm the environment.

To comply with the new leak rate threshold, owners and operators of commercial refrigeration equipment must conduct regular leak inspections and promptly repair any leaks that are detected. They must also keep records of their inspections and repairs for at least three years. Failure to comply with these requirements can result in penalties and fines.

In summary, the leak rate threshold for commercial refrigeration equipment with a full charge of 50 or more pounds of an HCFC refrigerant is 30% starting in 2019.

Answer:

a. 46.15%

b. 261.73 kg/s

c. 54.79 kW/K

Explanation:

a. State 1

The parameters given are;

T₁ = 560°C

P₁ = 12 MPa = 120 bar

Therefore;

h₁ = 3507.41 kJ/kg,  s₁ = 6.6864 kJ/(kg·K)

State 2

p₂ = 1 MPa = 10 bar

s₂ = s₁ = 6.6864 kJ/(kg·K)

h₂ = (6.6864 - 6.6426)÷(6.6955 - 6.6426)×(2828.27 - 2803.52) + 2803.52

= (0.0438 ÷ 0.0529) × 24.75 = 2824.01 kJ/kg

State 3

p₃ = 6 kPa = 0.06 bar

s₃ = s₁ = 6.6864 kJ/(kg·K)

sg = 8.3291 kJ/(kg·K)

sf = 0.52087 kJ/(kg·K)

x = s₃/sfg = (6.6864- 0.52087)/(8.3291  - 0.52087) = 0.7896

(h₃ - 151.494)/2415.17 = 0.7896

∴ h₃ = 2058.56 kJ/kg

State 4

Saturated liquid state

p₄ = 0.06 bar= 6000 Pa, h₄ = 151.494 kJ/kg, s₄ = 0.52087 kJ/(kg·K)

State 5

Open feed-water heater

p₅ = p₂ =  1 MPa = 10 bar = 1000000 Pa

s₄ = s₅ = 0.52087 kJ/(kg·K)

h₅ = h₄ + work done by the pump on the saturated liquid

∴ h₅ = h₄ + v₄ × (p₅ - p₄)

h₅ = 151.494 + 0.00100645 × (1000000 - 6000)/1000 = 152.4944113 kJ/kg

Step 6

Saturated liquid state

p₆ = 1 MPa = 10 bar

h₆ = 762.683 kJ/kg

s₆ = 2.1384 kJ/(kg·K)

v₆ = 0.00112723 m³/kg

Step 7

p₇ = p₁ = 12 MPa = 120 bar

s₇ = s₆ = 2.1384 kJ/(kg·K)

h₇ = h₆ + v₆ × (p₇ - p₆)

h₇ = 762.683  + 0.00112723 * (12 - 1) * 1000 = 775.08253 kJ/kg

The fraction of flow extracted at the second stage, y, is given as follows

\(y = \dfrac{762.683 - 152.4944113 }{2824.01 - 152.4944113 } = 0.2284\)

The turbine control volume is given as follows;

\(\dfrac{\dot{W_t}}{\dot{m_{1}}} = \left (h_{1} - h_{2} \right ) + \left (1 - y \right )\left (h_{2} - h_{3} \right )\)

= (3507.41  - 2824.01) + (1 - 0.22840)*(2824.01 - 2058.56) = 1274.02122 kJ/kg

For the pumps, we have;

\(\dfrac{\dot{W_p}}{\dot{m_{1}}} = \left (h_{7} - h_{6} \right ) + \left (1 - y \right )\left (h_{5} - h_{4} \right )\)

= (775.08253 - 762.683) + (1 - 0.22840)*(152.4944113 -  151.494)

= 13.17 kJ/kg

For the working fluid that flows through the steam generator, we have;

\(\dfrac{\dot{Q_{in}}}{\dot{m_{1}}} = \left (h_{1} - h_{7} \right )\)

= 3507.41 - 775.08253 = 2732.32747 kJ/kg

The thermal efficiency, η, is given as follows;

\(\eta = \dfrac{\dfrac{\dot{W_t}}{\dot{m_{1}}} -\dfrac{\dot{W_p}}{\dot{m_{1}}}}{\dfrac{\dot{Q_{in}}}{\dot{m_{1}}}}\)

η = (1274.02122 - 13.17)/2732.32747 = 0.4615 which is 46.15%

(762.683 - 152.4944113)/(2824.01 - 152.4944113)

b. The mass flow rate, \(\dot{m_{1}}\), into the first turbine stage is given as follows;

\(\dot{m_{1}} = \dfrac{\dot{W_{cycle}}}{\dfrac{\dot{W_t}}{\dot{m_{1}}} -\dfrac{\dot{W_p}}{\dot{m_{1}}}}\)

\(\dot{m_{1}}\) = 330 *1000/(1274.02122 - 13.17) = 261.73 kg/s

c. From the entropy rate balance of the steady state form, we have;

\(\dot{\sigma }_{cv} = \sum_{e}^{}\dot{m}_{e}s_{e} - \sum_{i}^{}\dot{m}_{i}s_{i} = \dot{m}_{6}s_{6} - \dot{m}_{2}s_{2} - \dot{m}_{5}s_{5}\)

\(\dot{\sigma }_{cv} = \dot{m}_{6} \left [s_{6} - ys_{2} - (1 - y)s_{5} \right ]\)

= 261.73 * (2.1384 - 0.2284*6.6864 - (1 - 0.2284)*0.52087 = 54.79 kW/K

Answer:

Mach number = 0.68168

The flow should be treated as compressible.

Explanation:

Given that:

The altitude of a commercial jet = 35000

The properties of air at that given altitude are as follows:

Pressure = 24.577 kPa

Temperature T = 50.78176° C

Temperature T = ( 50.78176 + 273 )K = 328.78176 K

\(\varphi = 0.38428 \ kg/m^3\)

The velocity is also given as: 550 mph = 245.872 m/s

Therefore, the sonic velocity is firstly determined by using the formula:

\(a = \sqrt{ \vartheta \times R \times T\\)

\(a = \sqrt{1.4 \times 287 \times 323.78176\)

\(a = \sqrt{130095.5112\)

a = 360.68755 m/s

Then, we can calculate the Mach number by using the expression:

\({Mach \ number = \dfrac{V}{a}}\)

\(Mach \ number = \dfrac{245.872}{360.68755}\)

Mach number = 0.68168

b) Ideally, all flows are compressible because the Mach number is greater than 0.3, suppose the Mach number is lesser than 0.3, then it is incompressible.

To calculate the average cost, divide the total purchase amount by the number of shares purchased to figure the average cost per share.

The average cost share method is commonly used by investors for mutual fund tax reporting.

Therefore average cost per share = Total cost/ total share owned.For example, an investor that has $1000in an investment and owns 500 shares would have an average cost basis of $2 i.e ($10,00 / 500).

Similarly,The total cost =$ 2.80+ $1.90 = $4.70

The total share owned = 500+ 1000 = 1500

average cost = 4.70/1500 = $0.0031 per share.

No, it is not possible to perform energy targeting using the numerical method with just one cascade. Multiple cascades are required to accurately determine the pinch point and optimize the energy system.

When performing energy targeting using the numerical method, the goal is to optimize the energy consumption and identify the pinch point in a given system. The pinch point is the location where the heat transfer requirements and available heat sources are the closest, and it represents the most energy-efficient operation of the system.

To determine the pinch point, a cascade analysis is performed, which involves dividing the heat exchanger network into several cascades or sections. Each cascade consists of a series of heat exchangers connected in a specific sequence. By analyzing the heat flow through each cascade, the pinch point can be identified.

The numerical method utilizes mathematical algorithms and calculations to solve the energy targeting problem. It involves solving a set of equations that describe the heat transfer and energy balances within the system. By considering multiple cascades, the numerical method can accurately account for the complex heat exchange interactions and identify the optimal configuration of the system.

Performing energy targeting with just one cascade would oversimplify the analysis and may lead to inaccurate results. The interactions between different heat exchangers and the overall heat transfer characteristics of the system cannot be adequately captured with a single cascade. Therefore, to obtain reliable and precise results, it is necessary to use multiple cascades in the numerical method.
