Flow Nets A grid obtained by drawing a series of streamlines and equipotential lines is known as a flow net. The flow net provide a simple graphical technique for studying two dimentional irrotational flows especially in the cases where mathematically relations for steam function and velocity function are either not available to are are rather difficult and cumbersome to solve. Use of flow nets: 1. Determaination of the design of the outlets for their streamlining. 2. Determaination of quantity of seepage and upward lift pressure bellow the hydraulic structure. 3. Determaination of the streamlines and equipotential lines. 4. Determaination of the pressure and velocity distribution, for given boundaries of flow. Limitations of flow nets: 1. The flow net analysis can not be a...
