Write the names of different types of flow

Write the names of different types of flow and explain them. The fluid flow is classified as:- 1.        Steady and unsteady flow 2.        Uniform and non-uniform flow 3.        Laminar and turbulent flow 4.        Compressible and incompressible flow 5.        Rotational and irrotational flow 6.        One,two and three dimensional flow (1). Steady flow:- Study flow is defined as flow types in which fluid characteristics like velocity, pressure, density, etc. at a point do not change over time.   Unsteady flow:-  Unsteady flow is the type of flow in which the speed, pressure or density at a point changes over time. (2). Uniform flow:-  Uniform flow is defined as the type of flow in which the velocity does not change in space at any point. ...
