Q2 2. A 50 HP, 440 volt single-phase motor is 92% efficient and operates at 88.2% power factor, lagging. It spins at N = 1600 RPM at full load. It weighs 320 kg.a) Calculate Pe, the electric power into the motor at full load in watts. (1HP = 746 W) b) Calculate the Line Current at full load c) Using 50 HP and 440 volts as base, what is the line current from b) in per-unit? d) What is the apparent power, S, of the motor at full load, in per unit on the 50 HP, 440 volt base?
