Steam at 800kpa and 300 degree celsius exists in the large supply line. when the valve opened from the large supply the steam enters into an empty, evacuated tank with a volume of 0.3m cube. when pressure in the tank reaches 100kpa the inlet valve is closed and the temperature in the tank is 150 degree celsius. the ambient temperature is 25 degree celsius. Determine if the process is possible from the SECOND LAW standpoint.
What is the theoretical maximum amount of work that could be done by a gas in a piston expanding from 10 L to 20 L (pressure of the surrounding atmosphere is 100 KPa)
A paddle wheel, inserted inserted into the volume, does 720 KJ of work on the air. If the volume is 2 cubic meters, calculate the entropy increase assuming constant specific heats.
