Correct Answer - Option 1 : incompressible
Explanation:
There are six types of fluid flow:
|
Compressible flow
|
- The flow in which the density is not constant which means the density of the fluid changes from point to point.
- The flow in which the density is constant which means the density of the fluid does not change from point to point.
|
|
Incompressible flow
|
|
Uniform flow
|
- The type of flow in which the velocity at any given time does not change with respect to space (i.e. length of direction of the flow).
- The type of flow in which the velocity at any given time changes with respect to space (i.e. length of the direction of the flow).
|
|
Non - uniform flow
|
|
Steady flow and
|
- Type of flow in which the fluid characteristics like velocity, density, pressure, etc at a point do not change with time.
- Type of flow in which the fluid characteristics like velocity, density, pressure, etc at a point change with time.
|
|
Unsteady flow
|
|
Rotational flow
|
- The type of fluid flow in which the fluid particles while flowing along streamlines and also rotate about their own axis.
- The type of fluid flow in which the fluid particles while flowing along streamline and do not rotate about their own axis.
|
|
Irrotational flow
|
|
Laminar flow
|
- The type of flow in which the fluid particles move along well-defined paths or streamline and all the streamlines are straight and parallel.
- The type of flow in which the fluid particles move in a zigzag way, the eddies formation takes place which is responsible for high energy loss.
|
|
Turbulent flow
|
|
1D flow
|
- The type of flow in which the flow parameter such as velocity is a function of time and one space coordinate only, say x.
- The type of flow in which velocity is a function of time and two rectangular space coordinates say x, y.
- The type of flow in which velocity is a function of time and three mutually perpendicular directions. The function of 3 space coordinates (x, y, z).
