    The required rated input apparent power is 14.98 HP

    Explanation:

    Real power input = real power output : efficiency

    real power output = 12 HP

    efficiency = 90% = 0.9

    Real power input = 12 : 0.9 = 13.33 HP

    Apparent power input = real power input : power factor = 13.33 : 0.89 = 14.98 HP
