3. a. a. A heat exchanger is designed to transfer heat from a supply of high temperature steam to oil, to heat the oil from 10°C to 35°C. There is no loss of heat to the surroundings. The steam enters the heat exchanger with a mass flow rate of 3 kg/s at 400°C and 300 kPa, and exits the exchanger as a saturated liquid. The oil remains a liquid during the heating with a constant specific heat of 1.78 kJ/kg-K. Assume steady state and constant pressure heating and cooling processes. Neglect kinetic and potential energy. How much oil can be heated in this exchanger, in kg/s? How much entropy is produced during this process?
