Pressure Differential

Written by Jerry Ratzlaff on . Posted in Thermodynamics

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

PRESSURE DIFFERENTIAL FORMULA

\(\large{ \Delta p = \frac {   1.59923 \; p \; d^4 \; \rho   }  { m_f^2 } }\)

\(\large{ \Delta p = Eu  \; \rho \;  U^2  }\)     (Euler number)        

Where:

\(\large{ \Delta p }\) = pressure differential

\(\large{ U }\) = characteristic velocity

\(\large{ Eu }\) = Euler number

\(\large{ \rho }\) (Greek symbol rho) = density of fluid

\(\large{ d }\) = pipe diameter

\(\large{ m_f }\) = mass flow rate

\(\large{ p }\) = pressure change
