Question

The pressure exerted due to a water column of height 100 m is

Answer 1

Answer:

The answer is 981 KPa.

Explanation:

Formula to calculate hydrostatic pressure is as below:

P = ρ g h    

Here

P = pressure in liquid S.I unit of pressure is N/m2.

ρ = density of the liquid. The density of the liquid is measured in kg/m3. ( Density of water is 1000 kg/m3)

g = acceleration of gravity value is 9.81 m/s2.

h = height of fluid column. It is measured in m.

Now let calculate the pressure.

P = ρ g h  

P = 1000 kg/m3 x 9.81m /s2 x 100m

P = 981000 kgm-1s-2 ( 1Pa = kgm-1s-2)

P = 981 KPa
