Question

A large vessel of height h is filled with a liquid of density

Answer 1

Your Complete question is-

A large vessel of height H, is filled with a liquid of density ρ, upto the brim. A small hole of radius r is made at the side vertical face, close to the base. The horizontal force is required to stop the gushing of liquid is

The horizontal force is required to stop the gushing of liquid is ρgHπr².

Given-

• Height of vessel = H
• Density of liquid = ρ
• Radius of hole = r

We know that force is equals to pressure into area.

F = P × A

Also pressure of liquid at height H is given as

P = ρ g H

A = π r²

By substituting the values we get

F = ρgHπr²

Answer 2

Answer:

2(rowgH)pier^2

Explanation:

This is the case of Variable mass System. Here the Force will be exerted due to change in the mass of liquid.
