## PRESSURE DIFFERENTIAL

Pressure differential is the pressure difference between two points of a system.

### PRESSURE DIFFERENTIAL FORMULA

$$\large{ \Delta p = \frac { 1.59923 p_c d4 \rho } { m^2 } }$$

Where:

$$\large{ \Delta p }$$ or $$\large{ p_d }$$ = pressure differential

$$\large{ d }$$ = pipe diameter

$$\large{ m }$$ = mass flow rate

$$\large{ p_c }$$ = change in pressure

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