A 6 pole 3 phase induction motor develops 30 H P including

A 6 pole 3 phase induction motor develops 30 H P including mechanical losses totalling 2 H P, at a speed of 950 RPM on 550 volt, 50 Hz mains. If the power factor is 0.88 and core losses are negligible, calculate: (i) The slip (ii) The rotor copper loss (iii) The total input power if the stator losses are 2 Kw (iv) The line current. (6)
