Reduced Pressure

Reduced pressure, abbreviated as \(p_r\), of a fluid is the actual pressure.

 

Reduced Pressure formula
\( p_r = p\;/\;p_c \)
Symbol	English	Metric
\( p_r \) = reduced pressure	\(lbf\;/\;in^2\)	\(Pa\)
\( p \) = pressure	\(lbf\;/\;in^2\)	\(Pa\)
\( p_c \) = critical pressure	\(lbf\;/\;in^2\)	\(Pa\)
