Answer:
The heat gain of the room due to higher efficiency is 2.84 kW.
Explanation:
Given that,
Output power of shaft = 75 hp
Efficiency = 91%
High efficiency = 95.4%
We need to calculate the electric input given to motor
Using formula of efficiency
We need to calculate the electric input
For, heigh efficiency
The reduction of the heat gain of the room due to higher efficiency is
Put the value into the formula
Hence, The heat gain of the room due to higher efficiency is 2.84 kW.
