Question $6$

It is proposed that a nozzle receives air at $2\frac{m}{s},300K,$ and $150$kPa. The air is to exit at $110$kPa, a temperature of $280K,$ and a velocity of $100\frac{m}{s}.$ The mass flow rate is $0\mathrm{.}1k\frac{g}{s}.$ The surface of the nozzle is kept at $270K.$ Assume that the air behaves as an ideal gas with constant specific heat, evaluate the rate of entropy generation for this process. Based on your answer, is this process possible?

Question $3($Homework$)$

Saturated water vapor enters the turbine of a Carnot cycle at a pressure of $10$MPa. A vapor$/$liquid mixture exits the condenser of the cycle. If the mass flow rate of the water through the cycle $125k\frac{g}{s},$ determine the net power produced in the cycle and the thermal efficiency of the cycle. What is the maximum possible efficiency of the cycle under these conditions? What is the thermal efficiency if the isentropic efficiency of the turbine is $70\%?$
