Steam at 35 bar and 600 degree K 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? If air [assumed to be an ideal gas with Cp= 29.3 J/(mol K)] entered the valve at 35 bar and 600 degree K and left at 7 bar, what would be its exit temperature and entropy change?
