Question

A cylindrical tank of height 4m is fully filled with water calculate the pressure exerted​

Answer 1

Given :-

Height = 4m

Take the density of water = $1000~kg/m^3$

Acceleration due to gravity = $m/s^2$

To Find :-

Pressure = ?

Solution :-

Formula to find pressure = $h.\rho.g$

Put the given values :-

= $4\times 1000\times 10$

Pressure = 40,000 Pa

Additional Information

➣ Pressure is the force acting normally on unit surface area.

It is a scalar quantity.

Its SI unit is $Nm^{-2}$ or pascal (Pa).

Formula to find pressure :-

$Pressure= \dfrac{Thrust}{Area}$

or

$Pressure= h.\rho.g$
