Electrical Analogy

Basic Aim of this Apparatus & Set Up is to verify the very fundamental Flow Net Rule Flow lines and Equipotential lines must always intersect at right angles. As we know, Ground Water flows through the voids in a soil which are interconnected. This flow may be called seepage, since the velocities are very small. Also such water flows from a higher energy to a lower energy and behaves according to the general principles of fluid mechanics.
