| What is the resistance of a device that consumes 0.26 W of electric power while drawing a current of 8.3 mA? |
Homework Answers
here,
the current drawn , I = 8.3 mA
I = 0.0083 A
let the resistance of the device be R
the power consumed , P = I^2 * R
0.26 = 0.0083^2 * R
solving for R
R = 3774 ohm
the resistance of the device is 3774 ohm

An oil pump is drawing 44kW of electric power while pumping oil with p = 860 kg/m^3 at a rate of 0.1 m^3/s. The inlet and outlet diameters of the pipe are 8cm and 12cm, respectively. If the pressure rise of oil in the pump is measured to be 500 kPa and the motor efficiency is 90 percent, determine the mechanical efficiency of the pump.
