The heat pump with a power input of 2000 kW draws heat from a heat source at 70 ° C and gives heat to a boiler. Thanks to the heat given to the boiler, the saturated liquid water entering the boiler at 300 kPa pressure leaves the boiler as saturated steam at 300 kPa (3bar) pressure. Since the performance of the heat pump (γ = COP_IP) is equal to 0.5 times the performance of the Carnot heat pump operating under the same temperature conditions, find the mass flow rate (kg / s) of the water flowing from the boiler. Note: The boiler works according to the open system SASA model. Changes in kinetic and potential energies for the boiler are negligible.

Question
- The heat pump with a power input of 2000 kW draws heat from a heat source at 70 ° C and gives heat to a boiler. Thanks to the heat given to the boiler, the saturated liquid water entering the boiler at 300 kPa pressure leaves the boiler as saturated steam at 300 kPa (3bar) pressure. Since the performance of the heat pump (γ = COP_IP) is equal to 0.5 times the performance of the Carnot heat pump operating under the same temperature conditions, find the mass flow rate (kg / s) of the water flowing from the boiler.
Note: The boiler works according to the open system SASA model. Changes in kinetic and potential energies for the boiler are negligible.
