Question

Calculate pressure exerted by water on the bottom of a deep dam of 12m from it's surface.(density of water is 1000kg/meter cube)

Answer 1

AnswEr :

Pressure exerted by water on the bottom of a deep dam(Hydrostatic pressure) is 120000 Pa.

Step-by-step Explanation :

GivEn :

• Density of water, ϱ = 10³kg/m³

• Height = 12 m

• g = 10m/s²

To find :

• Pressure exerted by water on the bottom of a deep dam(Hydrostatic pressure) = ?

SoluTion :

We know that,

$\sf \longrightarrow \: Hydrostatic \: pressure = \rho \times g \times h$

Substituting the values,

$\sf \longrightarrow \: Hydrostatic \: pressure = {10}^{3} \times 10 \times 12$

$\sf \longrightarrow \: Hydrostatic \: pressure = {10}^{4} \times 12$

$\sf \longrightarrow \: Hydrostatic \: pressure = 10000 \times 12$

$\sf \therefore { \blue{Hydrostatic \: pressure = 120000 \: Pa}}$

Hence, Pressure exerted by water on the bottom of a deep dam(Hydrostatic pressure) is 120000 Pa.
