QUESTIONS 1. Refrigerant-134a is cooled by water in a condenser. The refrigerant enters the condenser at a pressure of 1 MPa and a temperature of 70°C at a flow rate of 6 kg / min and exits at a temperature of 35 °C. Cooling water enters the condenser at 300 kPa pressure and 15 °C temperature and exits at 25 °C temperature. By neglecting pressure losses, Calculate; a) mass flow of cooling water b) the heat transfer from the refrigerant...
