Question
Pressure of a gas in a closed cylinder is expressed in the following way : $\text{P}=\text{P}_\text{a}+\text{h}\rho\text{g}$
Identify the expressions for:
  1. Absolute pressure of the gas.
  2. Gauge pressure of the gas.
✓

Answer

  1. Absolute pressure of the gas,
$P = P_a$
  1. Gauge pressure of the gas,
$\text{P}-\text{P}_\text{a}=\text{h}\rho\text{g}$
