Develop general computer flowsheet / programms for determining the
following properties of a non ideal multicomponent gaseous mixture
using Vander Waal equation of state;
a) molar volume
b) fugacity coefficient
c) specific enthalpy (J/Mol)
d) specific entropy (J/mol/k)
e) specific internal energy ( J/MOL)
    Test your programs by evaluating those properties for the
following mixtures
1) equimolar mixture of ethanol and benzene at 1 atm and 100 degree
celcius
2) a hydrocarbon mixture of 80% methane , 16% ethane and 5% propane at
10atm and 300 degree centigrade

Just out of sheer curiosity, what type of class is this associated
with (if any)? I've noticed a number of these questions that seem to
combine principles of both computer programming and some type of
science--either chemistry, physics or molecular biology, which I think
is great training. What is your major, or what type of work are you
doing?
