# Air Pressure Loss through Piping

## Formulas that use Air Pressure Loss through Piping

\(\large{ p_l = \frac { \mu \; l \; v_a{^2} \; \rho } {24 \; d \; g } }\) |

### Where:

\(\large{ p_l }\) = air pressure loss

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

\(\large{ \mu }\) (Greek symbol mu) = friction coefficient of air

\(\large{ v_a }\) = air velocity

\(\large{ g }\) = gravitational acceleration

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

\(\large{ l }\) = length of pipe
