P3. Control volume. Heat Exchanger: There is a flow heat exchanger countercurrent to cool 10kg/s of water vapor to 300"C and 600kPa to 60"C liquid saturated. It uses cooling water of 15"C and 100kPa going to 40"C. Calculate: A) The control volume: ... B) The enthalpies of each point . C) The heat flux radiating from 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
