One thousand kg of natural gas at 100 bar and 255 K is stored in a tank. If the pressure, p, specific volume, ??, and temperature, T, of the gas are related by the following expression p 5 [(5.18 3 1023 )Ty(?? 2 0.002668)] 2 (8.91 3 1023 )y??2 where ?? is in m3 /kg, T is in K, and p is in bar, determine the volume of the tank, in m3 . Also, plot pressure versus specific volume for the isotherms T 5 250, 500, and 1000 K. 1.34 A 2.2 m3 tank contains water vapor at 10340 kPa and 633 K. If the pressure, p, specific volume, ??, and temperature, T, of water vapor are related by the expression p 5 [(7183.04)Ty(?? 2 0.0169)] 2 (25.02 3 103 )y??2 where ?? is in m3 /kg, T is in K, and p is in kPa, determine the mass of water in the tank. Also, plot pressure versus specific volume for the isotherms T 5 667, 778, and 889 K
