A gas which obeys the equation of state, PV/RT=1 +BP ,
where B is a known
temperature-dependent parameter, is fed at a steady rate to an
insulated valve where its pressure is reduced from P1 to P2. Given
that the upstream temperature of the gas is T1 and that the
constant-pressure molar heat capacity of the gas in the ideal gas
state is given by Cp* = a + bT, where a and b are known constants,
derive an expression...
