Ammonia flowing at a rate of one mole per second is to be isothermally compresse

Question

Ammonia flowing at a rate of one mole per second is to be isothermally compressed in a flow turbine from 1 bar and 100oC to 50 bar. If the compression is done reversibly, compute the heat and work flows needed if ammonia obeys VW equation of state.
Hint: Use the thermodynamic definition, ( )

Explanation / Answer

The van der Waal's equation of state for a real gas is:

(P + n2a / V2)(V- nb) = nRT

The van der Waals equation of state approaches the ideal gas law PV=nRT as the values of these constants approach zero. The constant a provides a correction for the intermolecular forces and Constant b is a correction for finite molecular size.
