A steady flow device, internally reversible device operates sucj that the pressure of the fluid passing through it remains constant. Nitrogen enters this device at 250 C and leaves at 30 C. The device exchanges 500 kW of heat with its surroundings that remains at a constant 20 C. Use CASA to answer the following: A) Mass flow Rate through the device B) How much power does the device produce C)What is the rate at which the entropy of nitrogen changes? D) What is the rate at which the entropy of the surroundings changes? E) Does this system satisfy the second law?
