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. ...

Campare centrifugal pump and reciprocating pump

Campare centrifugal pump and reciprocating pump SN . Centrifugal pump Reciprocating pump 1. Its speed is high. Its speed is low. 2. It gives even flow of liquid. It gives fluctuating flow of liquid. 3. It has lower efficiency,at high heads and greater efficiency at low head. It has lower efficiency,at smaller heads and high efficiency at higher head. 4. It is suitable for low head and large discharge. It is suitable for higher heads and smaller discharge. 5. It can pump dirty water also. It can pump clear water only. 6. It is compact and occupies less space. It requires more space. 7. It’s initial cost is less. It’s initial cost is high. 8. It needs priming. It does not need priming. 9. Air vessels are not required. Air vessels are required. 10. ...
