Uniform and Non-Uniform Flow MCQ Quiz in தமிழ் - Objective Question with Answer for Uniform and Non-Uniform Flow - இலவச PDF ஐப் பதிவிறக்கவும்

Explanation:

Uniform flow is defined as the type of flow in which the velocity at any given time does not change with respect to space.

\({\left( {\frac{{\partial V}}{{\partial s}}} \right)_{t = const}} = 0\)

Non-Uniform flow is defined as the type of flow in which the velocity at any given time changes with respect to space.

\({\left( {\frac{{\partial V}}{{\partial s}}} \right)_{t = const}} \ne 0\)

Non - uniform Flow: When the fluid properties change with respect to space, the type of flow is known as Non - uniform flow.

Steady Flow: When the fluid properties do not change with respect to time, then the flow is known as steady flow.

Unsteady flow: When the fluid properties changes with respect to time, then the flow is known as unsteady flow.

Rotational flow: When the fluid particles rotate about their centre of mass, then the flow is known as rotational flow.

• The flow of liquid through a long pipe of constant diameter at a constant rate is a steady uniform flow
• The flow of liquid through a long pipeline of constant diameter, at either increasing or decreasing rate, is unsteady – uniform flow
• The flow of liquid through a tapering pipe at a constant rate is steady non – uniform flow
  ​
• The flow through a tapering pipe at either increasing or decreasing rate is unsteady – non – uniform flow.
