## Specific Heat Ratio

Specific heat ratio ( $$\gamma$$ ) (also called heat capacity ratio, adiabatic index, isentropic expansion factor) is the ratio of two specific heats.

### Specific Heat Ratio Formula

$$specific \; heat \; ratio \;=\; \frac { specific \; heat \; constant \; pressure } { specific \; heat \; constant \; volume }$$

$$\gamma = \frac {C_p } {C_v}$$

Where:

$$\gamma$$ (Greek symbol gamma) or $$\kappa$$ (Greek symbol kappa) = specific heat ratio

$$C_p$$ =

$$C_v$$ = specific heat constant volume
