Kindly comment for any further clarification and upvote if you find this solution helpful.
Output power rated is 100 HP
its working on 90% of full load.
so output power currently is 90% of 100 HP which is 90HP.
As 1 HP = 746 watts
Efficiency = 0.88 or 88%
Efficiency = Output Power / Input Power
Input power = Output Power / Efficiency
Input power = (90*746)/0.88
Input power = 76295.45 watt or 76.295 kW.
