Absolute Pressure

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

Absolute pressure is pressure that is measured from the starting point of 0 in a perfect vacuum.

FORMULA

\(p_a = p_g \;+\; p_{at} \)

Where:

\(p_a\) = absolute pressure

\(p_g\) = gauge pressure

\(p_{at}\) = atmospheric pressure

Solve for:

\(p_g = p_{at} \;+\; p_a \)

\(p_{at} = p_g \;+\; p_a \)
