Problem

Which mathematical expression correctly gives the gauge pressure at a depth

h

below the surface of an incompressible fluid of density

\rho

in a region where the gravitational acceleration is

g

? a)

P_{\text{gauge}} = \rho g h^{2}

P_{\text{gauge}} = \dfrac{1}{2}\rho g h

P_{\text{gauge}} = \rho g h

P_{\text{gauge}} = \rho g h + P_{\text{atm}}
