Hey there!

The American Petroleum Institute gravity, (API gravity), measures the heaviness of the liquid that we consider compared to water: if the value of API gravity is greater than 10, it is lighter and the liquid floats on water; if less than 10, it is heavier and sinks below.

The API can be given with the formula

where SG is the specific Gravity

Here we have the API = 65 , hence

The Specific Gravity (SG) is the ration between the density of the liquid to the density of water.

Hence

The PRESSURE AT A PARTICULAR HEIGHT CAN BE GIVEN WITH THE FORMULA

P = DENSITY OF THE LIQUID * HEIGHT

P = 43.52 lb / ft³ x 27 ft.

Hence P = 1175.04 lb / ft² is the pressure 27 ft. deep.

Cheers :)
