Saturated water vapor at 1000 kPa is throttled to 100 kPa. The velocity of the steam remains constant through the process. Determine the exit temperature of the water vapor. I know this is already awnsered in a solution for 1st edition but can someone help me understand what they do and how they picked the numbers they did from some table to get the exit temperature?
