An electric motor draws a current of 10 amperes (A) with a voltage of 110 V. The output shaft develops a torque of 9.5 N#m and a rotational speed of 1000 rpm. All operating data are constant with time. Determine
(a) the electric power required by the motor and the power developed by the output shaft, each in kilowatts;
(b) the net power input to the motor, in kilowatts;
(c) the amount of energy transferred to the motor by electrical work and the amount of energy transferred out of the motor by the shaft in kW# h and Btu, during 2 h of operation.
