Pressure Differential

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Pressure differential, abbreviated as \(\Delta p\), is the pressure difference between two points of a system.

 

PRESSURE DIFFERENTIAL formula

\(\large{ \Delta p = \frac {   1.59923 \; p \; d^4 \; \rho   }  { m_f^2 } }\) 
Symbol English Metric
\(\large{ \Delta p }\) = pressure differential \(\large{\frac{lbf}{in^2}}\)  \(\large{Pa}\) 
\(\large{ \rho }\) (Greek symbol rho) = density of fluid \(\large{\frac{lbm}{ft^3}}\) \(\large{\frac{kg}{m^3}}\)
\(\large{ d }\) = inside diameter of pipe \(\large{in}\) \(\large{mm}\)
\(\large{ m_f }\) = mass flow rate \(\large{\frac{lbm}{sec}}\) \(\large{\frac{kg}{s}}\)
\(\large{ p }\) = pressure change \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
