A brilliant young engineering student just invented a new chrome-plated digital heat exchanger that has water flowing through it at 14.41 kg/s. At the inlet, the water is a saturated vapor at 200.°C. The water passes isothermally through the heat exchanger while it absorbs heat from the environment.
At the outlet, the pressure is 1.00 MPa.
Determine (a) the heat transfer rate, and (b) the entropy production rate. (c) Show whether this device violates the second law of thermodynamics.
Assume that the system boundary temperature is isothermal at 200.°C.
