The coefficient of performance of a residential heat pump is 1.6. Calculate the heating effect in kJ/s this heat pump will produce when it consumes 4.5 kW of electrical power.

The heating effect of the residential heat pump will be 7.2 KJ/Sec

Explanation:

The rate of heat produced ()

Here, Coefficient of performance = 1.6

Here, Consume of electrical power =4.5

The rate of heat produced ( )  = Coefficient of performance × Consume of electrical power

   ∴ = 1.6 × 4.5

         = 7.2 KJ/SEC

∴ The heating effect of the residential heat pump will be 7.2 KJ/Sec
