Remarks

・Input P and Pc must be in the same unit.
・Input T and Tc must be in the same unit.
・P=R*T/(V/n-b)-a/(T0.5*V/n*(V/n+b)).
・a=0.42748*R2*Tc2.5/Pc.
・b=0.08664*R*Tc/Pc.
・z=P*V/(R*T)
・LaTex: \\\textup{Compressibility Factor}:z=\frac{PV}{RT}\\P=\frac{RT}{V-b}-\frac{a}{\sqrt{T} V\left ( V+b \right )}\\a=0.42748\left ( \frac{R^{2}T_{c}^{2.5}}{P_{c}}\right )\; ,b=0.08664\left (\frac{RT_{c}}{P_{c}} \right )
