COP=  (  frac{Q_r}{(Q_r   Q_a)}  )

TuteeHUB · Answer

COP=  (  frac{Q_a}{(Q_r   Q_a)}  )

TuteeHUB · Answer

COP=  (  frac{Q_r}{(Q_r   Q_a)}  )

TuteeHUB · Answer

COP=  (  frac{Q_a}{(Q_r + Q_a)}  )

TuteeHUB · Answer

COP=  (  frac{Q_a}{(Q_a   Q_r)}  )

1.	What is the coefficient of performance of the refrigerant system working on reversed Carnot cycle, having Q_a as heat absorbed by the air during isothermal expansion per kg of air and Q_r as heat rejected during isothermal compression per kg of air?
