$255 per hour

Total number of employed people = 16

(i) 5 people earn $15 per hour

That means that the total amount earned by those 5 is;

5 x $15 = $75 per hour

(ii) 4 people earn $17 per hour

That means that the total amount earned by those 4 is;

4 x $17 = $68 per hour

(iii) The remaining people earn $16 per hour.

There are 7 people remaining. i.e

16 - 5 - 4 = 7

That means that the total amount earned by those remaining (7) is;

7 x $16 = $112 per hour

The total hourly wage is therefore the sum of all the results in i, ii and iii. i.e

Total = $75 + $68 + $112

Total = $255

Therefore, the total hourly wage earned by all 16 people is $255

The return interval for a flood with a 5% chance of occurring in a given year is approximately 1.0526 years, or approximately 1 year and 21 days

The return interval for a flood with a 5% chance of occurring in a given year can be calculated using statistical methods. The return interval represents the average time period between occurrences of a specific event, such as a flood, with a certain probability. In this case, we want to determine the return interval for a flood with a 5% chance, also known as the 20-year flood.

To calculate the return interval, we need to use the concept of exceedance probability. The exceedance probability is the probability of a flood of a certain magnitude being equalled or exceeded in any given year.

1. Calculate the exceedance probability:

Exceedance probability = 1 - Probability of occurrence in a given year

In this case, the probability of occurrence in a given year is 5% (or 0.05). Therefore:

Exceedance probability = 1 - 0.05 = 0.95

2. Calculate the return interval:

Return interval = 1 / Exceedance probability

Return interval = 1 / 0.95 = 1.0526

It's important to note that this calculation assumes that the probability of a flood occurrence remains constant over time and that the occurrence of floods follows a random distribution. The return interval is a statistical estimate and should be interpreted as an average value. Actual flood events can vary significantly and may not precisely align with the calculated return interval.

Return intervals are commonly used in hydrology and floodplain management to assess flood risks, design infrastructure, and establish flood insurance rates. They provide a useful framework for understanding the frequency and magnitude of flood events, allowing for informed decision-making in riparian ecohydrology and management.

Answer:

Electricity

Explanation:

Without electricity, so many things cannot be accomplished.

Answer:

The right solution is:

(a) 24 sec

(b) 24 sec

Explanation:

The given values are:

Water inlet's flow rate,

= 0.4 m³/s

Water outlet's flow rate,

= 0.2 m³/s

(a)

The volume of water filled will be:

= \(Area(height)\)

= \(12(4.4-4)\)

= \(12\times 0.4\)

= \(4.8 \ m^3\)

Opening to closing time taken will be:

= \(\frac{4.8}{0.2}\)

= \(24 \ sec\)

(b)

Inlet's flow rate,

= 0

Outlet's flow rate will be:

= 0.2 m³/s

Closing to opening time taken will be:

= \(\frac{4.8}{0.2}\)

= \(24 \ sec\)

a. The time taken for the valve opening to closing is 24 seconds.

b. The time taken for the valve closing to opening is 24 seconds.

a.

First we need to determine the volume of the water

= Area * height

= 12*(4.4-4)

= 12*0.4

= 4.8

Now the time taken should be

= 4.8/0.2

= 24 seconds.

b. The time taken should be

= 4.8/0.2

= 2.4 seconds

Answer:

For most uses you'll want your water heated to 120 F(49 C) In this example you'd need a demand water heater that produces a temperature rise and it will take about 2 hours

This question is incomplete, the complete question is;

An air-standard Diesel cycle engine operates as follows: The temperatures at the beginning and end of the compression stroke are 30 °C and 700 °C, respectively. The net work per cycle is 590.1 kJ/kg, and the heat transfer input per cycle is 925 kJ/kg. Determine the a) compression ratio, b) maximum temperature of the cycle, and c) the cutoff ratio, v3/v2.

Use the cold air standard assumptions.

Answer:

a) The compression ratio is 18.48

b) The maximum temperature of the cycle is 1893.4 K

c) The cutoff ratio, v₃/v₂ is 1.946

Explanation:

Given the data in the question;

Temperature at the start of a compression T₁ = 30°C = (30 + 273) = 303 K

Temperature at the end of a compression T₂ = 700°C = (700 + 273) = 973 K

Net work per cycle \(W_{net\) = 590.1 kJ/kg

Heat transfer input per cycle Qs = 925 kJ/kg

a) compression ratio;

As illustrated in the diagram below, 1 - 2 is adiabatic compression;

so,

Tγ\(^{Y-1\) = constant { For Air, γ = 1.4 }

hence;

⇒ V₁ / V₂ = \((\) T₂ / T₁ \()^{\frac{1}{Y-1}\)

so we substitute

⇒ V₁ / V₂ = \((\)  973 K / 303 K  \()^{\frac{1}{1.4-1}\)

= \((\)  3.21122  \()^{\frac{1}{0.4}\)

= 18.4788 ≈ 18.48

Therefore, The compression ratio is 18.48

b) maximum temperature of the cycle

We know that for Air, Cp = 1.005 kJ/kgK

Now,

Heat transfer input per cycle Qs = Cp( T₃ - T₂ )

we substitute

925 = 1.005( T₃ - 700 )

( T₃ - 700 ) = 925 / 1.005

( T₃ - 700 ) = 920.398

T₃ = 920.398 + 700

T₃ = 1620.398 °C

T₃ = ( 1620.398 + 273 ) K

T₃ = 1893.396 K ≈ 1893.4 K

Therefore, The maximum temperature of the cycle is 1893.4 K

c)  the cutoff ratio, v₃/v₂;

Since pressure is constant, V ∝ T

So,

cutoff ratio S = v₃ / v₂  = T₃ / T₂

we substitute

cutoff ratio S = 1893.396 K / 973 K

cutoff ratio S = 1.9459 ≈ 1.946

Therefore, the cutoff ratio, v₃/v₂ is 1.946

Explanation:

Technician A is correct. The brake light switch is a safety feature that activates the brake lights when the brake pedal is pressed. When the switch is open, it interrupts the circuit and prevents the flow of electricity to the brake lights, causing both brake lights to not illuminate.

This is because the open switch breaks the connection between the brake lights and the power source.

Technician B's statement is incorrect. The back-up lights are not connected in parallel with the taillights. Instead, they are typically connected in parallel with the reverse gear switch. When the vehicle is put into reverse, the reverse gear switch completes the circuit, allowing electricity to flow to the back-up lights and illuminating them. The taillights, on the other hand, are connected to the headlight switch and are controlled separately from the back-up lights.

To summarize, Technician A is correct that if the brake light switch is open, neither brake light will illuminate. Technician B's statement about the back-up lights being connected in parallel with the taillights is incorrect.

We need to conduct standard Proctor compaction tests to develop the compaction plot for the silty clay soil. The degree of saturation of the compacted soil can be calculated using the formula. To determine the minimum cubic yards of the borrow pit soil required for the construction of the embankment, we can use the formula that takes into account the water content and dry unit weight of the soil.

(a) To develop the compaction plot for the silty clay soil, we need to conduct standard Proctor compaction tests. In this test, we measure the dry unit weight and moisture content of the soil at different compaction efforts. Then, we plot the dry unit weight versus the moisture content to get the compaction curve. The maximum dry unit weight and the corresponding optimum moisture content can be obtained from the compaction curve.

(b) The degree of saturation of the compacted soil in test 2 can be calculated using the following formula: Degree of Saturation = (Vw / VV) * 100, where Vw is the volume of water and VV is the volume of voids.

(c) To find the minimum cubic yards of the borrow pit soil required for the construction of the embankment, we can use the following formula:

Volume of soil required = Volume of embankment / (1 + (w / 100)) * γd

where w is the water content, γd is the dry unit weight, and the factor (1 + (w / 100)) accounts for the change in volume due to water content.

The sum of moments about A must be zero. The reaction moment at point A is 106 kN.m in the clockwise direction.

(a) To determine whether the structure is statically determinate or not, the first step is to count the number of unknown reactions. Here, we have three unknowns - the vertical reactions at A and C, and the reaction moment at A.Now let us make a cut in the structure at point A to 'explode' the structure. The following figure shows the exploded view of the structure. The cut divides the structure into two parts, and we have to consider the left and right parts of the structure separately in order to determine the unknown reactions. Since the right part of the structure is isolated, there are no external forces acting on it. Therefore, the sum of moments about A must be zero.

\($$-RA(2) + 6(4) + 12(2) = 0$$$$\Rightarrow RA = 18 \ kN.m$$\)

The left part of the structure can be treated as a simply supported beam carrying a uniformly distributed load of 2 kN/m between A and C. The vertical reactions at A and C can be determined by taking moments about C.

\($$- RA(2) - RC(10) + \frac{2 \times 8^{2}}{8} + \frac{2 \times 6^{2}}{8} + \frac{2 \times 4^{2}}{8} + \frac{2 \times 2^{2}}{8} = 0$$$$\Rightarrow RC = 11 \ kN$$$$\sum F_{y} = 0 \ \ \Rightarrow \ \ RA + RC = 2(2+4+6+8+10)$$$$\Rightarrow RA = 92 \ kN$$\)

Since the two values of RA do not match, the structure is not statically determinate.
(b) The reaction moment at point A can be determined by taking moments about A.

\($$M_{A} = -RC(10) + \frac{2 \times 8^{2}}{8} + \frac{2 \times 6^{2}}{8} + \frac{2 \times 4^{2}}{8} + \frac{2 \times 2^{2}}{8}$$$$\Rightarrow M_{A} = -11(10) + 4 + 9 + 4 + 1$$$$\Rightarrow M_{A} = -106 \ kN.m$$\)

The required ventilation rate is 400 cfm.

H = height office = 10 feet

W = width office = 20 feet

L = length office = 20 feet

ACPH = air change per hour = 6

Basically the formula to calculate the required ventilation rate is by multiply the ACPH with the space volume.

We know the office space have block shape with volume formula is H*W*L. So the required ventilation rate is,

Required ventilation rate = 6 * (10 * 20 * 20)

= 24,000 cubic feet per hour

Since the question want the result in cfm or cubic feet per minute, so we divide the result by 60 to convert that to cfm. So,

CFM = 24,000 / 60

The resulting pressure of the gas when its volume decreases is 300 kN/m².

Explanation:

Given;

initial volume of the gas, V₁ = 80 L

number of moles of the gas, n = 0.5 moles

initial pressure of the gas, P₁ = 150 kN/m² = 150 kPa

Determine the constant temperature of the gas using ideal gas equation;

PV = nRT

where;

R is ideal gas constant = 8.315 L.kPa/K.mol

T is the constant temperature

\(T = \frac{P_1V_1}{nR} \\\\T = \frac{150.kPa \ \times \ 80 .L}{0.5 .mol \ \times \ 8.315(L.kPa/mol.K)} \\\\T = 2,886.35 \ K\)

When the gas is compressed to half of its volume;

new volume of the gas, V₂ = ¹/₂ V₁

                                             = ¹/₂ x 80L = 40 L

The new pressure, P₂ is calculated as;

\(P_2V_2 = nRT\\\\P_2 = \frac{nRT}{V_2} \\\\P_2 = \frac{0.5 \times 8.315\times 2886.35}{40} \\\\P_2 = 300 \ kPa = 300 \ kN/m^2\)

Therefore, the resulting pressure of the gas when its volume decreases is 300 kN/m².

In an automotive four-stroke cycle engine, one cylinder completes a cycle every four strokes, consisting of intake, compression, combustion, and exhaust phases. This cycle is essential for the engine to generate power and propel the vehicle.

The four-stroke cycle, also known as the Otto cycle, is the most common combustion cycle used in internal combustion engines. It consists of four distinct strokes: intake, compression, combustion, and exhaust.

During the intake stroke, the piston moves downward, drawing in a mixture of fuel and air into the cylinder through the intake valve. In the compression stroke, the piston moves upward, compressing the fuel-air mixture to a higher pressure and temperature.

Next, in the combustion stroke, the spark plug ignites the compressed fuel-air mixture, causing a rapid combustion process. This generates high pressure, which forces the piston back down, creating power and driving the crankshaft.

Finally, in the exhaust stroke, the piston moves upward again, pushing the burned gases out of the cylinder through the exhaust valve. This prepares the cylinder for the next intake stroke, and the cycle repeats.

Overall, it takes four strokes, or two complete rotations of the crankshaft, for one cylinder in an automotive four-stroke cycle engine to complete a full cycle. This cycle is essential for the engine to convert the chemical energy in fuel into mechanical work, powering the vehicle.
