A pressure vessel is being designed to hold compressed methane to fuel a liquid rocket motor at a maximum pressure of 50 bar. If the methane is to be stored at 40 bar, -18 C, determine the mass contained in a 10 m3 tank using the following assumptions: a) The ideal gas equation of state. b) The van der Waals equation of state. c) Using CoolProp. Comment on the accuracy of each.

n this problem, we're going get a rough estimate the amount of uranium fuel it would take if the US recieved all its electrical power from nuclear power plants. The size of a power plant in normally given as the about of electrical power it can produce when running a full capacity. This electrical power produced can be very different than the mechanical or thermal power that was required to produce this electricity. For example, power plant might have a...
