A25-hp three-phase induction motor operates for a 440-vrms (line-to-line) three phase source and draws a line current of 35 a rms at a power factor of 83 percent lagging under rated full load conditions. the full load speed is 1750 rpm. under no load conditions the speed is 1797 rpm and the line current is 6.5 a rms at a power factor of 30 percent lagging. find the power loss and efficiency with full load, the input power with no load and the speed regulation.
