A 3.27 m^3 tank contains 100kg of nitrogen at 225 K. Determine the pressure in the tank, using the following:
a) the ideal-gas equation of state
b) the van der Waal equation of state
c) the Beattie-Bridgeman equation of state.
Compare your results with the actual value at 2000 kPa (i.e., give % error for each answer).
