Question

Pressure = weight density × depth

A 1.2-m-tall barrel is filled with water (with a weight density of 9800 N/m^3). Find the water pressure on the bottom of the barrel.

Answer 1

As we know that pressure due to water is given as

Pressure = (weight density) (Depth)

here we know that

weight density of water =
`9800 N/m^3`

height of the water = 1.2 m

now from above formula we have

`P = 9800 * 1.2`

`P = 11760 Pa`

so pressure due to water is given as 11760 Pascal
