Question

The type of flow in which the velocity at any given time does not change with respect to space is known as:
1. Laminar flow
2. Compressible flow
3. Uniform flow
4. Unsteady flow

Answer 1

Correct Answer - Option 3 : Uniform flow

Explanation: 

Laminar flow: Laminar flow occurs when the fluid flows in infinitesimal parallel layers with no disruption between them. In laminar flows, fluid layers slide in parallel, with no eddies, swirls, or currents normal to the flow itself. 

Compressible flow: In this type of flow density of fluid does not remain constant during the flow, it may change according to flow.

Uniform flow: If the velocity vector at all the points in the flow is the same at any instant of time then the flow is uniform flow.

Unsteady flow: If the fluid and flow characteristics at a point may change with time, then the flow is unsteady.
