Steam is expanded in a turbine from a pressure of p1=2mpa and temperature of t 400°c to a pressure of p2=15kpa and quality of x2=90%. the steam enters the turbine at a velocity of v= 50 m/s and exits the turbine at a velocity of v2=180m/s. assume that the turbine is adiabatic. find the work per kilogram of steam done by the turbine.

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 volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
