Specific Heat Ratio

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Specific heat ratio, abbreviated as \(\gamma\), is a dimensionless number, also called ratio of specific heat, heat capacity ratio, adiabatic index, isentropic expansion factor, is the ratio of two specific heats or the ratio of the heat capacity at constant pressure to heat capacity at constant volume.            

Specific Heat Ratio Formula

\(\large{ \gamma = \frac {C_p }   {C_v} }\)         

Where:

\(\large{ \gamma }\)   (Greek symbol gamma) = specific heat ratio

\(\large{ C_p }\) = specific heat constant pressure

\(\large{ C_v }\) = specific heat constant volume
