The maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor using time-delay fuses is approximately 45 A.

To determine the maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor, we can use the National Electrical Code (NEC) guidelines.

Step 1: Calculate Full Load Current (FLA)

The full load current (FLA) of a motor can be calculated using the formula:

\(\mathrm{FLA = \frac{Horsepower \times 746}{\sqrt{3}\times voltages \times efficiency \times power factor } }\)

Since efficiency and power factor are not given, we will assume typical values of 0.85 for efficiency and 0.85 for power factor.

Given:

Horsepower (HP) = 7.5 HP

Voltage = 208 V

Efficiency = 0.85

Power Factor = 0.85

Substitute these values into the formula:

\(\mathrm{FLA = \frac{7.5 \times 746}{\sqrt{3}\times 208 \times 0.85 \times 0.85 } }\)

Step 2: Determine the Maximum Rating:-

According to NEC guidelines, the maximum rating of the protective device can be calculated by multiplying the FLA by a percentage that corresponds to the type of motor and the type of protective device.

For a squirrel-cage induction motor with time-delay fuses, the percentage is typically around 175%.

Maximum Rating = FLA × 175%

Maximum Rating = 25.76A × 1.75 ≈ 45.12A

Rounded to the nearest standard fuse size, the maximum rating of the protective device is 45 A.

Answer:

During starts and stops

Explanation:

"Many of the energy inefficiencies in vehicles occur during starts and stops."

found it in the text.

The largest internal pressure that can be applied to the cylindrical tank is 1.55 MPa.

The ultimate normal stress of steel used is 450 MPa. The factor of safety is 5.0.

The maximum allowable stress is determined by dividing the ultimate normal stress by the factor of safety.

Hence, the maximum allowable stress is 450 MPa / 5.0 = 90 MPa.

The maximum internal pressure that can be applied to the cylindrical tank is determined by using the formula for the maximum hoop stress, which is given by P = 2S*t/D, where P is the maximum internal pressure, S is the maximum allowable stress, t is the wall thickness, and D is the outer diameter.

Substituting the given values, we get P = 2*90*0.016/1.75 = 1.55 MPa.

Answer:

\(y' = \frac{sec(x)}{3}[sin(3x) tan(x) + 3cos(3x)]\)

Explanation:

Given

\(\frac{sin3x\ secx}{3}\)

Required

The quotient rule

Quotient rule states that:

\(y' = \frac{V\frac{du}{dx} - U\frac{dv}{dx}}{v^2}\)

Where

\(v = 3\) and \(\frac{dv}{dx} = 0\)

\(u = sin3x\ secx\)

\(\frac{du}{dx}\) using product rule is:

\(\frac{du}{dx} = sin3x * \frac{d[secx]}{dx} + secx * \frac{d[sin3x]}{dx}\)

Differentiate all:

\(\frac{du}{dx} = sin(3x) sec(x) tan(x) + 3sec(x)cos(3x)\)

Factorize:

\(\frac{du}{dx} = sec(x)[sin(3x) tan(x) + 3cos(3x)]\)

So, the rule:

\(y' = \frac{V\frac{du}{dx} - U\frac{dv}{dx}}{v^2}\) becomes

\(y' = \frac{3[sec(x)[sin(3x) tan(x) + 3cos(3x)]] - [sin3x\ secx] * 0}{3^2}\)

Solving further:

\(y' = \frac{3[sec(x)[sin(3x) tan(x) + 3cos(3x)]]}{9}\)

\(y' = \frac{sec(x)[sin(3x) tan(x) + 3cos(3x)]}{3}\)

\(y' = \frac{sec(x)}{3}[sin(3x) tan(x) + 3cos(3x)]\)

Answer:

the angular acceleration of each drum depends on the applied force F. If the force is known, then the angular acceleration can be calculated. If the force is not known, then the angular acceleration cannot be calculated.

Explanation:

To find the angular acceleration of each drum, we can use the equation for rotational dynamics:

\(I * alpha = F * r\)

where I is the moment of inertia of the drum, alpha is the angular acceleration, F is the applied force, and r is the distance from the center of rotation to the point where the force is applied.

In this case, the moment of inertia of each drum is given by:

\(I = mr^2\)

where m is the mass of the drum and r is the radius of gyration. Substituting this expression into the equation above, we get:

\((m * r^2) * alpha = F * r\)

Solving for alpha, we find that:

\(alpha = F * r / (m * r^2)\)

Substituting the given values, we find that the angular acceleration of each drum is:

\(alpha = F * 250 mm / (105 kg * (370 mm)^2)\)

This equation can be simplified to:

\(alpha = F / (7.29 * 105 kg)\)

So the angular acceleration of each drum depends on the applied force F. If the force is known, then the angular acceleration can be calculated. If the force is not known, then the angular acceleration cannot be calculated.

When an ordinarily elastic material cracks brittlely, there is little or no outward trace of material deformation prior to failure.

The plastic deformation that occurs before failure is minimal or nonexistent in brittle fractures. Glasses, ceramics, as well as various polymers and metals, frequently fracture in a brittle way.

When a material is exposed to forces below its yield limit, brittle fractures take place. A ductile material is typically the foundation for machine design, and the design criteria are intended to prevent plastic and, in some circumstances, elastic deformations.

Material that has undergone either no plastic deformation or very little plastic deformation prior to fracture is said to have fractured with brittleness. Since they all share this quality, brittle materials include rock, concrete, glass, and cast iron.

Answer:

127.58 ft

Explanation:

We need first to calculate the length from corner to corner of the story, L.

Since the length of each floor is 75 ft and its width 50 ft, and since each floor is a rectangle with diagonal, L, using Pythagoras' theorem, we have

L² = (75 ft)² + (50 ft)²

= 5625 ft² + 2500 ft²

L² = 8125 ft²

L = √(8125 ft²)

L = 90.14 ft

Since the crane is 5 ft off the southwesterly corner of the building, the working radius, R = L + 5 ft = 90.14 ft + 5 ft = 95.14 ft.(since the diagonal length of the floor plus the distance of the crane from the south westerly corner add to give the working radius)

The boom tip height, H = height of building h + clearance of boom, h'

h = height of each story, h" × number of stories, n

Since h" = 15 ft and n = 5

h = 15 ft × 5 = 75 ft

Also, h' = 10 ft

So, H = h + h'

H = 75 ft + 10 ft

H = 85 ft

So, the minimum boom length, L' = √(H² + R²)

substituting the values of the variables into the equation, we have

L' = √(H² + R²)

L' = √((85 ft)² + (95.14 ft)²)

L' = √(7225 ft² + 9051.6196 ft²)

L' = √(16276.6196 ft²)

L' = 127.58 ft

A hammer and a wrench

Explanation:

The heat exchanger's estimated bare module price is $199,101.

The pricing of a bare module includes all necessary hardware and installation labour within a 3-meter radius. Investment = above plus royalties plus real estate plus supplies + legal + working capital plus construction-related interest Working capital is equal to 10%+ of invested fixed capital. This could differ greatly.

Bare module cost = (Cost of tubes + Cost of shell + Cost of bundle) x (Cost factor)

Tube length = \(160 / (2 x 1.3) = 61.54 m\)

Cost of tubes = \(61.54 x $50 = $3,077\)

Shell length = \(1.25 x 61.54 = 76.92 m\)

Cost of shell = \(1.5 x 76.92 x $500 = $57,690\)

Number of tubes = \(61.54 x 10 = 615\)

Assuming a cost per tube of $10, we get:

Cost of bundle =\(615 x $10 = $6,150\)

Bare module cost = \(($3,077 + $57,690 + $6,150) x 3 = $199,101\)

Explanation:

In a channel where a modem transmits a +2 voltage signal, the PMF of the output Y includes probabilities of 4/10 for +2, 3/10 for +1, 2/10 for 0, and 1/10 for -1. The probability of the output being equal to the input is 4/10, and the probability of the output being positive is 7/10.

To solve this problem, we'll use the given probabilities to determine the probability mass function (PMF) of the output Y of the channel.

(a) PMF of the output Y:

Let's define Y as the output of the channel after adding noise. The possible values of Y are determined by adding the noise terms to the input signal.

Y = +2 + 0 = +2 (with probability 4/10)

Y = +2 + (-1) = +1 (with probability 3/10)

Y = +2 + (-2) = 0 (with probability 2/10)

Y = +2 + (-3) = -1 (with probability 1/10)

Therefore, the PMF of Y is:

P(Y = +2) = 4/10

P(Y = +1) = 3/10

P(Y = 0) = 2/10

P(Y = -1) = 1/10

(b) Probability that the output is equal to the input:

We can see from the PMF that Y = +2 occurs with a probability of 4/10. Therefore, the probability that the output of the channel is equal to the input is 4/10.

(c) Probability that the output is positive:

The values of Y that are positive are +2 and +1. From the PMF, we can calculate the probability as follows:

P(Y > 0) = P(Y = +2) + P(Y = +1) = (4/10) + (3/10) = 7/10

Therefore, the probability that the output of the channel is positive is 7/10.

Such as rock or soil, that can hold fluids like water. Permeability, on the other hand, refers to the ability of a material to allow fluids to flow through it. Hydraulic gradient represents the slope or the change in hydraulic head (pressure) over a given distance.

In an aquifer, porosity plays a crucial role in determining how much water it can hold. High porosity means there are more empty spaces within the aquifer, which can hold larger amounts of groundwater. This is important for water storage and determines the aquifer's overall capacity.

Permeability influences the flow rate of groundwater in an aquifer. If the aquifer has high permeability, water can flow easily through it, resulting in faster groundwater movement. Conversely, low permeability limits the flow and slows down the movement of groundwater. Permeability is dependent on factors such as pore size and connectivity, as well as the presence of fractures or openings in the material.

The hydraulic gradient governs the direction and speed of groundwater flow within an aquifer. It is determined by the difference in hydraulic head between two points divided by the distance between them. A steeper hydraulic gradient signifies a greater change in pressure over a shorter distance, resulting in faster groundwater flow. In contrast, a gentle hydraulic gradient indicates slower groundwater movement.

In summary, porosity determines the storage capacity of an aquifer, permeability influences the flow rate of groundwater, and the hydraulic gradient governs the direction and speed of groundwater movement. These factors are interconnected and collectively impact the behavior of groundwater within an aquifer.
