The velocity potential function may be defined as a scalar function of space and time such that its derivative with respect to any direction gives the fluid velocity in that direction.
Velocity potential function (φ) satisfies the Laplace equation.
So \(\frac{{{\partial ^2}\phi }}{{\partial {x^2}}} + \frac{{{\partial ^2}\phi }}{{\partial {y^2}}} = 0\)
The solution of the above equation gives two sets of curves known as equipotential lines and stream lines (or flow lines), mutually orthogonal to each other as shown in figure.
The equipotential lines represent contours of equal head (potential).
The direction of seepage is always perpendicular to the equipotential lines.
The path along which the individual particles of water seep through the soil are called streamlines or flow lines.
