The Redlich-Kwong equation of state is given by RT a v(v +b)/T where R = the universal gas constant [= 0.518 kJ/(kg K)], T = absolute temperature (K), p = absolute pressure (kPa), and v = the volume of a kg of gas (m3/kg). The parameters a and b are calculated by RT2.5 a = 0.427. Pe Te b = 0.0866R- Pe where pc 4600 kPa and Tc = 191 K. you are asked to determine the amount of methane fuel that can be held in a 3-m3 tank at a temperature of -40 C with a pressure of 65,000 kPa.
