Flow net can be drawn only if the flow is distortion.
Explanation:
Flow net is a graphical representation of two-dimensional flow through porous media. It consists of a series of flow channels and equipotential lines that intersect at right angles. Flow nets are used to determine the flow rate, direction, and pressure in a porous medium. Flow nets are drawn based on the assumption that the flow is steady, two-dimensional, and incompressible. In addition, flow nets can only be drawn when the flow is distortion.
Distortion flow:
Distortion flow is a flow that changes the shape of the flow domain. In distortion flow, the flow lines are not straight and parallel, and the equipotential lines are not straight and perpendicular. Distortion flow occurs when the flow domain is not uniform, and there are variations in the hydraulic conductivity or the boundary conditions.
Why distortion flow is required for flow net?
Flow nets can only be drawn when the flow is distortion. This is because distortion flow results in a non-uniform flow field, and the flow lines and equipotential lines intersect at right angles. In addition, distortion flow allows for the calculation of the flow rate, direction, and pressure in a porous medium.
Other flow types:
Turbulent flow and rotational flow are not suitable for flow net analysis because they do not meet the assumptions of steady, two-dimensional, and incompressible flow. Turbulent flow is characterized by irregular and chaotic motion, while rotational flow is characterized by vortex formation.
Conclusion:
In conclusion, flow net can be drawn only if the flow is distortion. Distortion flow results in a non-uniform flow field, which allows for the calculation of the flow rate, direction, and pressure in a porous medium. Turbulent flow and rotational flow are not suitable for flow net analysis because they do not meet the assumptions of steady, two-dimensional, and incompressible flow.
