Dean Smith is dissatisfied with the time it takes to get a new faculty ID made and believes more servers will speed up service and reduce costs thanks to shorter lines. Prof. Karen is tasked to study the situation. Prof. Karen observes an average of 20 customers/hr arriving and each technician (service window) serves 5 customer/hr, on average. Assume an M/M/s queue system. Prof. Karen calculates the operational cost of each server as $20/hr, and assumes a cost of waiting in the SYSTEM as $25/hr per customer. What is the optimal number of service windows to minimize total cost

Answers

Answer 1
The answer is :

X = 4

Explanation:
Answer 2

The optimal number of service windows to minimize total cost will be 5 service windows.

How to calculate the optimal value?

The optimal number of service windows to minimize total cost will be calculated thus:

Cost = 20x + 25(20 - 5x)

Cost = 20x + 500 - 125x

Cost = 500 - 105x

For the minimum cost,

500 - 105x = 0

105x = 500

x = 500/105

x = 4.76 = 5

Therefore, the optimal number of service windows to minimize total cost will be 5 service windows.

What’s the relationship among speed frequency and the number of poles in a three phase induction motor

Answers

Answer:

The number of poles in the windings defines the motor's ideal speed. A motor with a higher number of poles will have a slower rated speed but a higher rated torque.

Explanation:

The relationship among speed, frequency, and the number of poles in a three-phase induction motor is governed by what is known as the synchronous speed equation.

The synchronous speed of an induction motor is the speed at which the rotating magnetic field generated by the stator windings of the motor rotates.

The synchronous speed (Ns) of a three-phase induction motor is given by the following equation:

Ns = (120 × f) / P

where:

Ns is the synchronous speed in revolutions per minute (RPM).

f is the supply frequency in hertz (Hz).

P is the number of poles.

From the equation, it can be observed that the synchronous speed is directly proportional to the frequency and inversely proportional to the number of poles.

This means that if the frequency increases, the synchronous speed also increases, assuming the number of poles remains constant.

Conversely, if the frequency decreases, the synchronous speed decreases.

The actual speed of an induction motor is known as the rotor speed or slip speed, which is always slightly lower than the synchronous speed. The difference between the synchronous speed and the actual speed is referred to as slip and is necessary for the motor to induce a voltage in the rotor and generate torque.

It's important to note that the synchronous speed equation assumes an ideal motor with no load. In practice, the actual speed of the motor depends on various factors, including the load torque, rotor resistance, and motor design.

Unemployment may result in increased payments from the state and federal governments for things like food stamps because unemployed persons tend to spend less and may accumulate more debt. Thus, option A is correct.

What hardest when high unemployment occurs?

High unemployment causes a decline in inflation. Voters and policymakers do not like dropping prices; they seek low unemployment and low inflation. They typically have to choose between the two and cannot usually have both.

Unemployed workers go through financial difficulties, which has an impact on their families, interpersonal relationships, and communities. If neglected, this can lead to a recession or even a depression as consumer spending, one of an economy's key sources of growth, falls.

Therefore, Land production is hit the hardest when high unemployment occurs.
