Question

Find the hydrostatic pressure exerted on an object that is 4.45 m below the surface of gasoline and its absolute pressure. The density of gasoline is 680 kg/m3.

Answer 1

Hydrostatic pressure equal: $p_h=\rho_ggh=680*9.81*4.45=30018.6$ Pa

Absolute pressure equal: $p=p_0+p_h=101300+30018.6=131318.6$ Pa
