A refrigeration cycle is executed with R-134a under the saturation dome between the pressure limits of 2 MPa and 0.2 MPa. If the power consumption of the refrigerator is 3 kW, the maximum rate of heat removal from the cooled space of this refrigerator is

Show neat and clear work

Water is put into the boiler at 23oC and 10 bar pressure, where the water will turn into steam saturated at constant pressure. Find of the process and heat required for production 15000 m3 /h slightly under the above conditions. Assume that the velocity of water entering the pot is ignored and steam is known leaves the kettle through a tube with an inner diameter of 0.15 m. The inlet and outlet of the pipe has same height

Kindly olve this problem, Thank you
