NCERT Solutions For Class 11 Physics Chapter 10: Mechanical Properties of Fluids

Content Curator

NCERT Solutions for Class 11 Physics Chapter 10 Mechanical Properties of Fluids are given in this article. Fluids are substances that can flow e.g., liquids and gases. It does not possess definite shape. When an object is submerged in a liquid at rest, the fluid exerts a force on its surface normally.

Class 11 Physics Chapter 10 Mechanical Properties of Fluids belongs to Unit 7 Properties of Bulk Matter which has a weightage of 20 marks in the Class 11 Examination along with Unit 8 and Unit 9. NCERT Solutions for Mechanical Properties of Fluids covers concepts of Pascal’s law, Archimedes Principle, and Viscosity.

Class 11 Physics Chapter 10 – Concepts Covered

Pressure is the thrust experienced per unit area of the surface of a liquid that is at rest.

The pressure at any point in the liquid depends on the depth (h) below the surface, density of liquid and acceleration due to gravity.

Pascal’s Law states that the pressure applied to an enclosed liquid is transmitted to every portion of the liquid and walls of the containing vessel.

\(P = {F \over A}\)

Archimedes Principle: When a body is either partially or fully immersed in a liquid, it loses some of its weight. The loss in the weight of the body is equal to the weight of the liquid that is displaced by the immersed part.

The upward force that’s exerted by the liquid displaced when a body is immersed is known as buoyancy.

The energy possessed by a liquid by the virtue of its pressure is known as pressure energy.

Pressure energy of liquid in volume dV = PdV

Bernoulli’s Theorem: For an incompressible, irrotational, and non-viscous liquid with a streamlined flow, the sum of the kinetic energy, pressure energy, and potential energy per unit mass is a constant

\({P \over \rho} + {v^2 \over 2}+gh=constant\)
