# 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

$$\large{ p_r = \frac {p}{p_c} }$$
Symbol 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 $$\large{\frac{lbf}{in^2}}$$ $$Pa$$
