### NCERT Solutions for Class 11 Physics Chapter 10

NCERT Solutions for Class 11 Physics Chapter 10 Mechanical Properties of Fluids help students to understand this fundamental chapter of Physics. This will create a strong basic understanding and interest in the student about fluid mechanics. The student will learn about pressure, viscosity, surface tension, etc in-depth with relevant formula and equations.

Let us discuss the sub-topics in detail.

10.1: Introduction:

The student will study some common physical properties of liquids and gases.

10.2: Pressure:

It is the force applied unit area of the surface. The pressure is a scalar quantity.

10.2.1: Pascalâ€™s Law:

Pascal saw during experiments that the pressure in a fluid at rest is the same at all points at the same height.

10.2.2: Variation of Pressure with Depth:

The student will study that pressure varies with depth also.

10.2.3: Atmospheric Pressure and Gauge Pressure:

These two pressures are very important to know for the students.

10.2.4: Hydraulic Machines:

The student will study that a number of devices like hydraulic lift and hydraulic brakes are based on Pascalâ€™s law.

10.3: Streamline flow:

It is a path of a fluid particle under steady flow.

10.4: Bernoulliâ€™s principle:

Fluid flow is a complex phenomenon although we can obtain some useful properties for streamline flows using the Bernoulliâ€™s principle.

10.4.1: Speed of Efflux: Torricelliâ€™s Law:

This is the speed of a freely falling body given in the form of the equation.

10.4.2: Venturi-meter:

It is a device to measure the flow speed of the incompressible fluid.

10.4.3: Blood Flow and Heart Attack:

The student will come to know that Bernoulliâ€™s principle helps in explaining about blood flow in the artery.

10.4.4: Dynamic Lift:

Dynamic lift is the force which acts on a body for example s airplane wing

10.5: Viscosity:

Viscosity is the resistance to fluid motion which is like internal friction similar to friction when a solid moves on a surface.

10.5.1: Stokesâ€™ Law:

This law states that the viscous force is proportional to the velocity of the object and is opposite to the direction of motion.

10.6: Reynolds number:

It is a dimensionless number giving value for an approximate idea about the turbulence of flow.

10.7: Surface tension:

It is an important phenomenon occurring at the surface of the liquid.

10.7.1: Surface Energy:

It is a form of energy-related with surface tension and is existing due to the attraction between molecules of the liquid.

10.7.2: Surface Energy and Surface Tension:

The student will learn the mutual relationship between surface tension and surface energy.

10.7.3: Angle of Contact:

It is the angle between tangents to the liquid surface at the point of contact with a solid surface inside the liquid.

10.7.4: Drops and Bubbles:

Students will study some properties of drops and bubbles in this section.

10.7.5: Capillary Rise:

It is a very important fact related to fluids. It is the cause of rising of liquid.

10.7.6: Detergents and Surface Tension:

It is the direct application of surface tension.
