" So is this power input to the motor?"
No, it is actually the output power of the motor. To get the input power to the motor you just divide it by the efficiency, remembering that the input is greater.
(output power)/(Input power) = efficiency
Input power = (output power)/(efficiency)
Input Watts to this particular motor = [(10hp)*(746W/hp)] /(.85) = 8776.5 Watts
Pin=Pout/eff=10/.85=11.76 hp.
Rick is correct .ASWe need more input.11.6
Power i watts =11.6x746
85% of 10HP = 8.5 HP
A compressor motor provides 10 hp to a pump. if the motor is 85% efficient , What is the power input to the motor ?
