Question

calculate the pressure exerted by a 76cm height of water column on its base

Answer 1

Given:

Height of water column, h= 76 cm= 0.76 m

To Find:

Pressure exerted by a 76cm height of water column on its base

Solution:

We know that,

• Pressure 'P' exerted by liquid on the base of its container is given by

$\pink{\boxed{\bf{P=\rho\:gh}}}$

where,

ρ is the density of liquid

g is acceleration due to gravity

h is the height of liquid

• Density of water= 1000 kg/m³

$\rule{190}{1}$

Now,

Let the pressure by given height of water column on its base be 'P'

So,

$\longrightarrow\rm{P=\rho gh}$

$\longrightarrow\rm{P=1000\times9.8\times0.76}$

(Taking g= 9.8 m/s²)

$\longrightarrow\rm\green{P=7448\:Pa}$

Hence, the pressure exerted by a 76cm height of water column on its base is 7448 Pa.
