A ground water tank has its height 2m. Calculate the pressure at its bottom when it is completely filled with water.​
Law Incorporation [45]

The pressure at the bottom : 19600 N/m²

<h3>Further explanation</h3>

Given

A ground water tank has its height 2m

Required

The pressure at its bottom

Solution

Hydrostatic pressure is the pressure caused by the weight of a liquid.  

The weight of a liquid is affected by the force of gravity.  

The hydrostatic pressure of a liquid can be formulated:  

\large{\boxed{\bold {P_h ~ = ~ \rho.g.h}}

Ph = hydrostatic pressure (N / m², Pa)  

ρ = density of liquid (kg / m³)  

g = acceleration due to gravity (m / s²)  

h = height / depth of liquid surface (m)  

ρ = density of water (kg / m³) = 1000

g = acceleration due to gravity = 9.8 m/ sec²

The pressure

\tt P=1000\times 9.8\times 2=19600~N/m^2
