Question 4 [30] Steam at 35 bar and 600K enters a throttling valve that reduces the steam pressure to 7 bar. Assuming there is no heat loss from the valve, what is the exit temperature of the steam and its change in entropy? a. Use steam tables. [15] b. Steam obeys the Peng-Robinson equation of state. Use an appropriate MATHCAD code. insert a PDF output of the code in your solution. Make sure to include your name and student number in the code. [15]
