Interpretation Introduction

Interpretation:

The depth of water at which the gate rises and permits water to flow under it is to be calculated.

Concept Introduction:

The force (F)

acting on a surface due to a fluid above it is defined as:

  F=ρgzA .......(1)

Here, ρ is the density of the fluid with height z , A is the area of the surface, and g is the acceleration due to gravity.

The force that leads any object to float when immersed partially or fully in a fluid is known as buoyancy or buoyant force. It is the result of the pressure differences that acts on the opposite sides of that object when immersed in the fluid which is static.

The tendency of any object to resist any kind of change in the velocity of that object is known as inertia.
