Answer:

a) the power loss due to irreversible head loss is 4.57 kW

b) the efficiency of the piping is 95%

c) the electric power output is 72.9918 kW

Explanation:

Given the data in the question below;

Irreversible loses \(h_L\) = 7m

Total head, H = 140 m

flow rate Q = 4000 L/min = 0.0666 m³/s

Generator efficiency n₀ = 84% = 0.84

we know that density of water is 1000 kg/m³

g = 9.81 m/s²

a) power loss due to irreversible head loss \(P_L\) is;    

\(P_L\) = p × Q × g × \(h_L\)

we substitute

\(P_L\) = 1000 × 0.0666 × 9.81 × 7

\(P_L\) = 4573.422 W

\(P_L\) = 4573.422 / 1000

\(P_L\) = 4.57 kW

Therefore, the power loss due to irreversible head loss is 4.57 kW

b) the efficiency of the piping n is;

n = (Actual head / maximum head) × 100

n = (( H - \(h_L\) ) / H) × 100

so we substitute

n = (( 140 - 7 ) / 140) × 100

n = (133/140) × 100

n = 0.95 × 100

n = 95%

Therefore, the efficiency of the piping is 95%

c) the electric power output if the turbine-generator efficiency is 84 percent;

n₀ = \(Power_{outpu\) / \(power_{inpu\)

\(Power_{outpu\) = n₀ × \(power_{inpu\)

\(Power_{outpu\) = n₀ × ( pQg( H - \(h_L\) ))

so we substitute

\(Power_{outpu\) = 0.84 × ( 1000 × 0.0666 × 9.81( 140 - 7 ))

\(Power_{outpu\) = 0.84 × 653.346( 133)

\(Power_{outpu\) = 0.84 × 86895.018

\(Power_{outpu\) = 72991.815 W

\(Power_{outpu\) = 72991.815 / 1000

\(Power_{outpu\) = 72.9918 kW

Therefore, the electric power output is 72.9918 kW

Answer:

a. From Y to X

b. q = 15 C

Explanation:

a.

When current is denoted by double subscript, it is interpreted as traveling from 1st subscript to the second, when the value of current is positive. On the other hand, if the value of current is negative, then it means that the current is traveling from 2nd subscript to the 1st subscript. Since, the value of current is negative in the given question, therefore, it means that the current is traveling from 2nd subscript to the 1st subscript. Hence the direction of current or the flow of electrons is:

From Y to X

b.

Using the following formula of current:

I = q/t

where,

I = Current (Absolute Value) = 3  A

q = amount of charge = ?

t = time taken = 5 s

Therefore,

3 A = q/5 s

q = (3 A)(5 s)

q = 15 C

Answer:

is the same probability and statistics that you can see in other areas, is just the topics that are indeed applied to engineering. The most important are those associated with normal distribution for both samples and population and stochastic processes since both of them are widely used in the engineering field. For example, in a manufacturing plant you can create an stochastic model which describes the process you need to evaluate. Other fields like machine learning, artificial intelligence, computer graphics, randomized algorithms, image processing, and scientific simulations also need a basic knowledge in probability and statistics.

Probability and statistics for engineers are methods of data analysis that are used in the design and manufacture of goods, structures, and systems by engineers.

Engineers can make well-informed decisions about complex systems and processes using these techniques. Engineers utilize probability and statistics to make decisions about systems, process design, and process control in a wide range of industries. Probability and statistics are critical tools for engineers because they help them make decisions based on empirical data rather than guesswork.

Probability is the likelihood or chance that something will happen. Probability is used in engineering to forecast and model the behavior of systems, the reliability of parts, and the chance of failure. Engineers can use probability to determine how likely a system or component is to fail. This knowledge can help engineers determine what types of materials to use in the design of components and systems, as well as how to design systems to prevent failure.

Statistics is the study of data, including its collection, analysis, interpretation, and presentation. Engineers utilize statistics to evaluate the performance of systems and the reliability of components. Engineers also use statistical methods to analyze data in order to optimize processes, reduce costs, and improve quality. Engineers can use statistical methods to determine if a process is operating correctly and to identify the root cause of process problems.

In addition, engineers can use statistical methods to determine how a process can be improved to increase efficiency and quality.

Answer:

  (x, y) = (5.76, 1 5/7)

Explanation:

The location of the centroid in the x-direction is the ratio of the first moment of area about the y-axis to the total area. Similarly, the y-coordinate of the centroid is the first moment of area about the x-axis, divided by the area.

For the moment about the y-axis, we can define a differential of area as ...

  dA = (y2 -y1)dx

where y2 = √(x/k2) and y1 = k1·x^3

The distance of that area from the y-axis is simply x.

So, the x-coordinate of the centroid is ...

  \(\displaystyle c_x=\frac{a_x}{a}=\frac{\int{x\cdot dA}}{\int{dA}}\\\\a_x=\int_0^{12}{x(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{5k_2^{1/2}}\cdot12^{5/2}-\frac{k_1}{5}12^5\\\\a=\int_0^{12}{(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{3k_2^{1/2}}\cdot12^{3/2}-\frac{k_1}{4}12^4\\\)

For k1 = 4/12^3 and k2=12/4^2, these evaluate to ...

  \(a_x=115.2\\a=20\\c_x=5.76\)

The y-coordinate of the centroid requires we find the distance of the differential of area from the x-axis. We can use (y2 +y1)/2 for that purpose. Then the y-coordinate is ...

  \(\displaystyle c_y=\frac{a_y}{a}\\\\a_y=\int_0^{12}{(\frac{y_2+y_1}{2}(y_2-y_1))}\,dx=\frac{1}{2}\int_0^{12}{(\frac{x}{k_2}-(k_1x^3)^2)}\,dx\\\\a_y=\frac{12^2}{4k_2}-\frac{k_1^212^7}{14}=\frac{240}{7}\\\\c_y=\frac{12}{7}\approx1.7143\)

The centroid of the shaded area is ...

  (x, y) = (5.76, 1 5/7)

Answer:

\(250\ \text{lbm/min}\)

\(625\ \text{ft/min}\)

Explanation:

\(A_1\) = Area of section 1 = \(10\ \text{ft}^2\)

\(V_1\) = Velocity of water at section 1 = 100 ft/min

\(v_1\) = Specific volume at section 1 = \(4\ \text{ft}^3/\text{lbm}\)

\(\rho\) = Density of fluid = \(0.2\ \text{lb/ft}^3\)

\(A_2\) = Area of section 2 = \(2\ \text{ft}^2\)

Mass flow rate is given by

\(m=\rho A_1V_1=\dfrac{A_1V_1}{v_1}\\\Rightarrow m=\dfrac{10\times 100}{4}\\\Rightarrow m=250\ \text{lbm/min}\)

The mass flow rate through the pipe is \(250\ \text{lbm/min}\)

As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1

\(m=\rho A_2V_2\\\Rightarrow V_2=\dfrac{m}{\rho A_2}\\\Rightarrow V_2=\dfrac{250}{0.2\times 2}\\\Rightarrow V_2=625\ \text{ft/min}\)

The speed at section 2 is \(625\ \text{ft/min}\).

(a) The mass flow rate will be "250 lbm/min".

(b) At section 2, the speed will be "625 ft/min".

According to the question,

Section 1 area, A₁ = 10 ft²

Section 2 area, A₂ = 2 ft²

Water's velocity, V₁ = 100 ft/min

Volume at section 1, v₁ = 4 ft³/lbm

(a) We know the formula,

Mass flow rate, m = ρA₁V₁

                              = \(\frac{A_1 V_1}{v_1}\)

By substituting the values,

                              = \(\frac{10\times 100}{4}\)

                              = \(\frac{1000}{4}\)

                              = 250 lbm/min

(2) The speed will be:

→ m = ρA₂V₂

or,

  V₂ = \(\frac{m}{\rho A_2}\)

By substituting the values,

       = \(\frac{250}{0.2\times 2}\)

       = \(\frac{200}{0.4}\)

       = 625 ft/min
