Question

N1 and n2 moles of two ideal gases having adiabatic constants

Answer 1

If n 1 and n 2 are moles of two ideal gases and having adiabatic constants y 1 ( gamma 1 ) and y 2 ( gamma 2 ) respectively have mixed cv for the mixture will be given below :

$C_{v} = n_{1} Cv_{1} + n_{2} Cv_{2} / n1 + n2\\C_{v} = n_{1} [ R / γ_{1} - 1 ] + n_{2} [ R / γ_{2} - 1 ] / n_{1} + n_{2} \\\\C_{v} = R [ n_{1} / γ_{1} -1 + n_{2} / γ_{2} -1 ] / n_{1} + n_{2}$
