Estimate the temperature of the first gas to flow out of the turbine.

Propane is available from a reservoir at 350 K and 1 MPa. An evacuated cylinder is attached to the reservoir manifold, and the cylinder is filled adiabatically until the pressure is 1 MPa. What is the final temperature in the cylinder? Ethane at 425 K and 100 bar initially is contained in a 1 m3 cylinder. An adiabatic, reversible turbine is connected to the outlet of the tank and exhausted to atmosphere at 1 bar absolute.

(a)Estimate the temperature of the first gas to flow out of the turbine.

(b)Estimate the rate of work per mole at the beginning of this operation.
