Aheat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 350°c enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. chlorine gas enters the exchanger at 1 bar and 28.0°c and leaves the exchanger at 140.0°c. assume the heat exchanger is adiabatic. what is the specific enthalpy of the inlet steam stream? (use liquid water at 0.01°c as a reference state.)

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
