Answer:Given
Cop=5
Driving power/ work input=35kw
Cop of heat pump= heat rejected to higher temperature reservoir (Q1)/work input
5= Q1/35kw
Q1= 175KW
THEREFORE heat transferred from system is 175KJ/s
Q1=Q2+W Q2= heat taken from lower temperature reservoir
175-35=Q2
Q2= 140 KJ/s
Heat transferred to fluid is 140 kj/s
