What are the properties of the flow net?

Following properties of flow, net are considered before preceding for construction and application of flow nets.

  1. Flow lines and equipotential lines cut each other at right angles i.e. they are mutually orthogonal.
  2. Each field is an approximate square and in a well-constructed flow net, one should be able to draw a circle touching all four sides.
  3. In a homogeneous soil, every transition in the shape of two types of curves will smooth, being either elliptical or parabolic in shape.
  4. The rate of flow through each flow channel is the same.
  5. The same potential drop occurs between two successive equipotential lines.
