What is the relation between CP and CV?

What is the relation between CP and CV?

The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Monoatomic gas has only one translational motion, hence three translational degrees of freedom.

What is the value of CP?

The nominal values used for air at 300 K are CP = 1.00 kJ/kg. K, Cv = 0.718 kJ/kg. K,, and k = 1.4.

What is dQ dT in thermodynamics?

In fact, the heat capacity C describes the amount of heat dQ involved in changing one mole of a substance by a given temperature increment dT: dQ = CdT.

Does specific heat ratio change with pressure?

The specific heat of dry air – CP and CV – will vary with pressure and temperature. This may influence on the accuracy of industrial air handling process calculations.

What is the importance of ratio of specific heat?

The ratio of the specific heats γ = CP/CV is a factor in adiabatic engine processes and in determining the speed of sound in a gas. This ratio γ = 1.66 for an ideal monoatomic gas and γ = 1.4 for air, which is predominantly a diatomic gas.
