Question

Define fluid machine and write down their three categories

Answer 1

Answer:

Fluids are defined as substance that flow or deform under the applied shear stress. Fluid has no definite shape of its own. It assumes the shape of its container. Liquids and gases are known as fluids. Depending on the behavior of fluids, fluids are divided into two types.Jul

Explanation:

1. Ideal Fluid:

An Ideal Fluid is a fluid that has no viscosity. It is incompressible in nature. Practically, no ideal fluid exists.

2. Real Fluid:

Real fluids are compressible in nature. They have some viscosity.

Examples: Kerosene, Petrol, Castor oil

3. Newtonian Fluid:

Fluids that obey Newton’s law of viscosity are known as Newtonian Fluids. For a Newtonian fluid, viscosity is entirely dependent upon the temperature and pressure of the fluid.

Examples: water, air, emulsions
