Question

Your centrifugal pump costs approximately $30 to run each day. Your facility is charged 9.7 cents per kilowatt hour for electricity, and all pumps in your facility use 240 VDC. What is the resistance of the copper wire supplying electricity to this pump?

Answer 1

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm

Explanation:

Given

Per day cost of running centrifugal pump is $30

Charge of electricity is 9.7 cents per kilowatt hour

Total electricity power consumed

`(30)/(0.097) \\309.278` kilowatt hour

Current flowing through the pump

`= (309.278)/(240) \\= 1.288`A

Resistance of the pump

`(1.288)/(240) \\0.005` ohm

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm
