An electric motor draws a current of I= 10 amp with a voltage of 110 V, as shown in the figure below, where hA = 3.5 W/K. The output shaft develops a torque of = 9.727 N-m and a rotational speed of 1000 RPM. For operation at steady state, determine for the motor (a) the magnitude of the electric power required, in kW. (b) the power developed by the output shaft, in kW. (c) the average surface temperature, Ts, in °C, if heat transfer occurs by convection to the surroundings at T = 21°C.
