Explain the relationships among speed, frequency, and the number of poles in a three-phase induction motor

1 answer:

5 0

The synchronous speed (rpm) equals 60 times the frequency divided by the number of pole pairs. For 50Hz, a two-pole motor will have a synchronous speed of 3000 rpm, a four-pole motor of 1500 rpm.

The actual speed is a few percent lower due to the slip of the asynchronous motor.

The slip increases with the torque, typical values are 5–10%. The rated speed for a four-pole motor at 50Hz will thus be something like 1360 rpm. At no-load, the slip is very small.

What industry cannot rely on estimation

jeka94

There is no industry which can not relay on estimation, all industries needs estimation.

The two primary categories of this profession are construction and manufacturing, according to the Bureau of Labor Statistics. It states that more than half of all cost estimators work in the construction industry, where they may further specialize in projects for homes, businesses, industries, or the government.

Cost estimation aids in setting the project budget, planning the required work, and managing new resources. Cost estimates are also of the utmost importance when trying to win over new clients. Before starting actual building, property owners also utilize cost estimates to evaluate the viability of their projects.

igor_vitrenko [27]

Answer:

$489,512.15

Explanation:

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value

P = Present value

R = interest rate

N = number of years

We are supposed to determine the present value

Present value is the sum of discounted cash flows

Present value can be calculated using a financial calculator

Cash flow in year 1 = 84,000

Cash flow in year 2 = 113,000

Cash flow in year 3 = 125,000

Cash flow in year 4 = 130,000

I = 6%

PV = 387,739.47

387,739.47(1.06)^4 = $489,512.15

To find the PV using a financial calculator:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.

3. Press compute
