A certain gas has a molecular weight of 30.0 a critical temperature of 310K. and a critical pressure of 4.5MPa. Calculate the density in kg/m3 of this gas at 465 K and 9.0MPa
(a) If the gas is ideal and
(b) If the gas obeys the law of corresponding states.
Derive a Differential Equation which will show how temperature in the tank changes with time. State assumption used. Solve this model to obtain T(t) given that T(t=200s) = 50°C.
Consider an engine that operates at a low temperature of 25C and a higher temperature of 432C. Would it be possible to have an efficiency of 65% ?
