Arigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 4 mpa. now the valve is opened, and steam is allowed to flow into the tank until the pressure reaches 4 mpa, at which point the valve is closed. if the final temperature of the steam in the tank is 550°c, determine the temperature of the steam in the supply line and the flow work per unit mass of the steam.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volume for a gas is much higher than the average volume for a liquid. d)-there is no difference.
