Reduced Pressure

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	\(\large{\frac{lbf}{in^2}}\)	\(Pa\)
