Answer:

input power of the geothermal motor will be 0.4166 hP

Explanation:

We have given shaft output = 0.25 hP

hP is known as horse power which is unit of measuring the power of motor

Efficiency of motor is given as efficiency = 60 % = 0.6

We have to fond the heat supply by the fan motor Q

We know that efficiency of any motor is the ratio of shaft power and input power

So $0.6=\frac{0.25}{P_0}$

So $P_0=\frac{0.25}{0.6}=0.4166hP$

So input power of the geothermal motor will be 0.4166 hP
