P3. Control volume. Heat Exchanger: There is a counter current flow heat exchanger to cool 4.5kg/s of water vapor at 300*C and 400kPa at 55*C saturated liquid. It uses cooling water of 15"C and 100kPa going to 85 C. Calculate: A) The control volume: B) The enthalpies of each point ..... ... C) The flow of heat radiated by the system. D) The flow of heat gained by the refrigerant .... E) The mass flow of the refrigerant .. F ) Present the diagram of data and results
