I am not sure I am stuck on this and I have been for 45 min someone please help me and this girl or boy!!
Answer:
W=2 MW
Explanation:
Given that
COP= 2.5
Heat extracted from 85°C
Qa= 5 MW
Lets heat supplied at 150°C = Qr
The power input to heat pump = W
From first law of thermodynamics
Qr= Qa+ W
We know that COP of heat pump given as



W=2 MW
For Carnot heat pump


2.5 T₂ - 895= T₂
T₂=596.66 K
T₂=323.6 °C
