TE 303 - HW #2, P7 - An Application of Equations of State - 25 pts

A 0.016773 m3 tank contains 1 kg of R-134a at 110oC. Determine the pressure of the refrigerant using:

a.) The Ideal Gas EOS
b.) The Compressibility Factor EOS
c.) The R-134a Tables
d.) The van der Waal EOS
e.) The Soave-Redlich-Kwong EOS

In your analysis, be sure to discuss a comparison of these equations of states (5 points).

You can get omega (acentric factor) from the NIST webbook. Look up your substance at saturation (T or P) for some range of values, and it gives you other "auxiliary data", including density, MW, and omega.
