# Reduced Temperature

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Reduced temperature, abbreviated as $$T_r$$, of a fluid is the actual temperature.

### Reduced Temperature Formula

$$\large{ T_r = \frac {T}{T_c} }$$

Where:

$$\large{ T_r }$$ = reduced temperature

$$\large{ T_c }$$ = critical temperature

$$\large{ T }$$ = temperature
