Please answer A and B, and show each step neatly. I will be sure to give thumbs up. Thank you

Consider a water-cooled condenser in a large refrigeration system in which R-134a is the refrigerant fluid. The refrigerant enters the condenser at 1.0 MPa and 60C, at the rate of 2 kg/s. and exits at 0.80 MPa and 40C. Cooling water enters the condenser at 10C and exits at 20 C at atmosphere pressure (100 kPa), Determine (a) The mass flow rate of cooling water (b) The heat transfer rate from the refrigerant to water Carwal
