    The equivalent circuit of a 220-V, three-phase, 4-pole, Y-connected, 60-Hz induction motor showed in the diagram has
    For a slip of 2.5%

    There are four things to find,
    (1) the total input power
    (2) the air gap power
    (3) the output mechanical torque
    (4) the efficiency

    I attached the circuit diagram.

    Not very clear but hope you can see it because I juz scanned it.
    Hope that expert could give me some guide to do this question.
