Answers

Answer 1

Answer:

Explanation:

From the given information;

There is no change or any difference in velocity in between the inlet and the outlet.

Therefore by using Bernoulli's equation, we have:

$\dfrac{V_1^2}{2g}+ \dfrac{P_1}{\gamma}+ z_1 + Epump= \dfrac{V_2^2}{2g}+ \dfrac{P_2}{\gamma}+ z_2+ H_L$

By dividing like terms on both sides, the equation is reduced to:

$z_1 + E_{pump} = z_2+H_L \\ \\ E_{pump} =(z_2-z_1)+H_L$

where;

$\Delta z = 400$

$\Delta z = z_2-z_1$

$\text{total head loss}= 408.5$

$E_{pump} =(400)+408.5$

$E_{pump} = 808.5 \ ft$

The required power input can be determined by using the formula:

$P= \dfrac{\gamma_wQH_{pump}}{\eta}$

Assuming the missing pump efficiency = 70% and the flow rate Q= 1.34

Then:

$P= \dfrac{62.40\times 1.34 \times 808.5}{0.7}$

$P = \dfrac{96576.48 \ ft.lb/s}{550\dfrac{ ft*lb/s}{hp}}$

P = 175.594 hp

The average repair cost of a microwave oven is 55$, with a standard deviation of 8$. the costs are normally distributed. If 12 ovens are repaired, find the probability that the mean of the repair bills will be greater than 60$.

Answers

The probability that the mean of the repair bills for 12 microwave ovens will be greater than $60 is 0.015 or about 1.5%.

What is Probability?

The distribution of the sample means for repair costs of 12 microwave ovens can be approximated to a normal distribution, with a mean of the population repair cost, μ = $55 and a standard deviation of the sample mean, σ/√n = $8/√12 ≈ $2.31.

We need to find the probability that the sample mean is greater than $60. Using the formula for z-score:

z = (x - μ) / (σ / √n)

= (60 - 55) / (2.31)

≈ 2.16

We can look up the area under the standard normal distribution curve for z-score 2.16 in a z-table or calculate it using software. The probability is approximately 0.015.

Therefore, the probability that the mean of the repair bills for 12 microwave ovens will be greater than $60 is 0.015 or about 1.5%.

T/F : The voltage through a resistor with current i(t) in the s-domain is sri(s).

Answers

False.

The voltage through a resistor with current i(t) in the s-domain is simply Ri(s), where R is the resistance value of the resistor. In the s-domain, the relationship between voltage and current through a resistor can be expressed using Ohm's law as V(s) = I(s)R.

Therefore, the voltage across a resistor in the s-domain is proportional to the current through it, with the proportionality constant being the resistance value. It's important to note that this relationship only holds true for resistive elements in linear circuits. Non-linear circuit elements such as diodes and transistors have much more complex voltage-current relationships that cannot be described using a simple linear equation.

According to Ref. 213/91, fire extinguishing equipment can be frozen True or False

Answers

False. Fire extinguishing equipment cannot be frozen according to Ref. 213/91.

According to Ref. 213/91, fire extinguishing equipment cannot be frozen. Fire extinguishers are essential safety devices designed to combat fires effectively. They contain pressurized agents that are specifically formulated to extinguish different types of fires. Freezing temperatures can significantly impair the functionality of fire extinguishers and render them ineffective in emergency situations.

When fire extinguishing equipment freezes, several issues can arise. First, the contents of the extinguisher may expand as they freeze, potentially leading to ruptures or leaks in the container. This can cause the extinguisher to malfunction or become hazardous when used. Second, freezing temperatures can affect the performance of the extinguishing agent itself. Certain agents, such as water-based solutions, can solidify or lose their effectiveness when exposed to extreme cold.

It is crucial to store fire extinguishers in suitable environments that are above freezing temperatures. This ensures that the equipment remains in optimal condition and is ready for immediate use during emergencies. Regular inspections and maintenance are also essential to identify any signs of damage or deterioration that may compromise the functionality of fire extinguishers.

describe potential errors due to trim heel and transducer separations in ships

Answers

Answer:

Trim heel and transducer separations are two potential errors that can affect the accuracy of a ship's draft and trim readings.

Trim heel refers to the angle of inclination of a ship in the water, which can affect the readings taken by the ship's sensors. If the ship is not perfectly level in the water, the sensors may not provide accurate measurements of the draft or the amount of cargo on board. This can result in incorrect calculations of the ship's stability, which can lead to dangerous situations.

Transducer separation is another potential source of error that can affect the accuracy of a ship's draft readings. Transducers are sensors that are mounted on the hull of a ship to measure the water level and provide information on the ship's draft. If these sensors are not properly calibrated or if they are separated from the hull, they may provide inaccurate readings, which can lead to errors in the ship's stability calculations.

In summary, trim heel and transducer separations can result in inaccurate readings of a ship's draft and cargo load, which can affect the ship's stability and safety. It is important for ship operators to regularly calibrate and maintain their sensors to minimize the risk of errors due to trim heel and transducer separations.

Make an accurate estimate of the number and length of joists and headers required to construct the floor frame for a single story rectangular building. The joists will be 12’ long and the headers will be 32’ along each of the 2 walls

Answers

To construct the floor frame for a single-story rectangular building, the number and length of joists and headers required depend on the size of the building.

To make an accurate estimate of the number and length of joists and headers, one can use the following steps:Step 1: Determine the size of the buildingTo determine the size of the building, one needs to know the length and width of the building. Let's assume the length of the building is 30 feet, and the width is 20 feet.Step 2: Calculate the distance between the joistsThe distance between the joists depends on the weight the floor needs to support. The standard spacing for joists is 16 inches on center.

To calculate the number of joists, divide the length of the building by the spacing between the joists. For example, 30 feet divided by 16 inches equals 23.4375. Round up to the nearest whole number to get 24. t 1. Therefore, 1 header is required.The number of headers can be determined by using this formula:Number of Headers = (Width of Building / Length of Headers) + 1Step 5: Calculate the total length of the headersThe headers will be 32 feet long along each of the 2 walls, so multiply the number of headers by 32 to get the total length of the headers. For example, 1 header multiplied by 32 feet equals 32 feet.

Therefore, 32 feet of headers are required.In conclusion, to construct the floor frame for a single-story rectangular building with a length of 30 feet and a width of 20 feet, 24 joists of 12 feet length and 32 feet of headers along each of the 2 walls are required. The total length of the joists required is 288 feet, while the total length of the headers required is 32 feet.

The magnitude of σ1 that will cause yielding according to the maximum-shear-stress theory is 9.94 ksi.

Yield stress for the zirconium-magnesium alloy, σY = 15.3 ksi

In-plane principal stresses are σ1 and σ2 = −0.54σ1

To find the maximum shear stress theory, the equation used is τ_max=1/2(σ1-σ2)

The maximum shear stress theory states that yielding begins when the maximum shear stress in a part equals or exceeds the shear strength of the material. It is represented as τ_max = τ_yield

Where τ_max is the maximum shear stress in a part and τ_yield is the shear strength of the material. In-plane principal stresses are σ1 and σ2 = −0.54σ1

Let us replace the value of σ2 in terms of σ1σ2 = −0.54σ1,σ1 = 1.85σ2

Substitute the values in the τ_max=1/2(σ1-σ2)

τ_max=1/2(σ1-(-0.54σ1))

τ_max=0.77σ1

Now, τ_yield= σY/2 = 7.65 ksi

Therefore, 0.77σ1 = 7.65

A simply supported beam of square cross section, is subject to a moment 51 kNm. The beam is of uniform sectional and geometric properties, with an E value of 201 GPa. If the radius of curvature of the beam under the action of the applied bending moment is 142147 mm,
what is the dimensional value of the beam's cross-section, that would be squared to determine its cross-sectional area?
Present your answer in millimeters, to three decimal places.

Answers

The dimensional value of the beam's cross-section, which would be squared to determine its cross-sectional area, is 2010 mm².

To find the dimensional value of the beam's cross-section, we can use the formula for the moment of inertia (I) of a square cross-section beam, which is given by (b * h³) / 12, where b is the base length and h is the height of the square cross-section.

Since the beam is subject to a bending moment, we can relate the moment of inertia (I) to the radius of curvature (R) using the formula I = E * (b * h³) / 12 * R, where E is the Young's modulus.

Rearranging the equation, we can solve for (b * h³), which represents the dimensional value of the beam's cross-section squared: (b * h³) = (12 * I * R) / (E).

Substituting the given values, I = 51 kNm, R = 142147 mm, and E = 201 GPa (or 201000 MPa), we can calculate the dimensional value of the cross-section squared: (b * h³) = (12 * 51 kNm * 142147 mm) / (201000 MPa).

Calculating the right side of the equation, we find that (b * h³) is approximately equal to 8590800 mm⁴.

To determine the dimensional value of the beam's cross-section, we need to find the square root of (b * h³), which gives us √(8590800 mm⁴) ≈ 2930 mm².

Therefore, the dimensional value of the beam's cross-section, which would be squared to determine its cross-sectional area, is 2010 mm².

By using order of magnitude analysis, the continuity and Navier-Stokes equations can be simplified to the Prandtl boundary-layer equations. For steady, incompressible, and two-dimensional flow, neglecting gravity, the result is delta u/ delta x + delta v/ delta y= 0; u delta u/ delta x +v delta u/ delta y= -1/p(delta u/ delta x)+ v delta^2 u/ delta y^2 Use L and V0 as characteristic length and velocity, respectively. Non-dimensionalize these equations and identify the similarity parameters that result.
