### An oil of specific gravity 0.9 is contained in a vessel. At a point the height of oil is 40m. Find the corresponding height of water at the point.

1 Answers

This question is based on Pascal’s Law. It states that pressure at any point in a fluid is always same in all directions.

Now,

This question can be solved by using the following formula :-

Given,

Specific gravity of water (So) = 0.9

Height of oil ( Zo) = 40 m

Now,

Density of oil = Specific gravity of oil × density of water

=> 0.9 × 1000

=> 900 kg/m3

Intensity of pressure = Density of oil × g × height of oil

=> 900 × 9.8 × 40

=> 352800 N/m2

So, putting these values in above equation we get ,
