Types Of Fluid Flow in a Pipe- Basic Of fluid Mechanics
The type of flow of a liquid depends upon the manner in which the particles unite and move. Though there are many types of flows, yet the following are important :
1. Uniform flow:
A flow, in which the liquid particles at all sections of a pipe or channel have the same velocities, is called a uniform flow.
2. Non-uniform flow:
A flow, in which the liquid particles at different sections of a pipe or channel have different velocities, is called a non-uniform flow.
3. Streamline flow:
A flow, in which each liquid particle has a definite path and the paths of individual particles do not cross each other, is called a streamline flow.
4. Turbulent flow:
A flow, in which each liquid particle does not have a definite path and the paths of individual particles also cross each other, is called a turbulent flow.
5. Steady flow:
A flow, in which the quantity of liquid flowing per second is constant, is called a steady flow. A steady flow may be uniform or non – uniform.
6. Unsteady flow:
A flow, in which the quantity of liquid flowing per second is not constant, is called an unsteady flow.
7. Compressible flow:
A flow, in which the volume of a fluid and its density changes during the flow, is called a compressible flow. All the gases are considered to have compressible flow.
