Hydrostatic Pressure Measurement

Question :

Calculate the hydrostatic pressure generated at the bottom of this vessel (in units of PSI) when it is completely filled with water:

Calculate the hydrostatic pressure

Now calculate the hydrostatic pressure at the bottom of this vessel (in units of PSI) when it is completely filled with gasoline (density = 42 lb/ft3 ):

hydrostatic pressure measurement calculation

What do you think the pressure will be at the bottom of the vessel if it is exactly half-full of gasoline and half-full of water, with a gasoline-water interface at the 5.5 foot mark? Explain your reasoning.

hydrostatic interface measurement calculation

Answer :

Hydrostatic pressure when completely full of water = 4.769 PSI

Hydrostatic pressure when completely full of gasoline = 3.208 PSI

Hydrostatic pressure when water-gasoline interface is at the 50% level = 3.988 PSI
