PRESSURE DIFFERENTIAL

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

PRESSURE DIFFERENTIAL FORMULA

\(pressure \; differential   \;=\;    \frac {   1.59923 \; change \; in \; pressure \;\;x\;\;  \left( \; pipe \; diameter  \;\;x\;\; 4  \; \right)   \;\;x\;\;  fluid \; density  }  { mass \; flow \; rate^2 } \)

\(\Delta p = \frac {   1.59923 p_c d4   \rho       }{ m^2 } \)

Where:

\(\Delta p\) or \(p_d\) = pressure differential

\(p_c\) = change in pressure

\(m\) = mass flow rate

\(d \) = pipe diameter

\(\rho\) (Greek symbol rho) = fluid density
