Repeat Problem 5.9 assuming that helium is described by the Peng-Robinson equation of state.

Problem 5.9

High-pressure helium is available from gas producers in 0.045-m³ cylinders at 400 bar and 298 K. Calculate the explosion equivalent of a tank of compressed helium in terms of kilograms of TNT. Assume helium is an ideal gas.
