# Reduced Pressure Calculator - Reduced Properties at Critical Point

Posted by Dinesh onUse this thermodynamics calculator to calculate reduced pressure of state variables normalized by the fluid's state properties at its critical point.

The reduced pressure is calculated as its actual pressure p is divided by its critical pressure p_{c}.

## Reduced Pressure Calculation

### Formula:

P_{r} = p / p_{c}

p

_{c}- critical pressure,

p - actual pressure,

P

_{r}- reduced pressure
