Steam enters a turbine with a pressure of 3000 kPa, a temperature of 400 degrees C and a velocity of 160 m/sec. Steam exits as a saturated vapor at 100 degrees C with a velocity of 100 m/sec. At steady state, the turbine develops work at a rate of 540 kJ/kg. Heat transfer occurs at a rate of -22.6 kJ/kg and at an average outer surface temperature of 350 K.

a. How much net exergy is carried into the turbine by the steam? 692.2 kj/kg

b. How much exergy leaves the turbine in the form of work? 540 kj/kg

c. How much exergy leaves the turbine in the form of heat? 3.36 kj/jg

d. What is the rate of exergy destruction of the turbine? 148.8 kj/kg

Those are the answers but with the formulas in the book I cant get any of them or anything similar(rounding)
