Pressure Differential
Pressure differential, abbreviated as \(\Delta p\), is the pressure difference between two points of a system.
PRESSURE DIFFERENTIAL formula
| \(\large{ \Delta p = \frac { 1.59923 \; p \; d^4 \; \rho } { m_f^2 } }\) |
Where:
| Units | 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 | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
