# Reduced Pressure

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Reduced pressure, abbreviated as $$p_r$$, of a fluid is the actual pressure.

## Reduced Pressure formula

 $$\large{ p_r = \frac {p}{p_c} }$$

### Where:

 Units English Metric $$\large{ p_r }$$ = reduced pressure $$\large{\frac{lbf}{in^2}}$$ $$Pa$$ $$\large{ p }$$ = pressure $$\large{\frac{lbf}{in^2}}$$ $$Pa$$ $$\large{ p_c }$$ = critical pressure $$\large{\frac{lbf}{in^2}}$$ $$Pa$$
