Compute channel properties 5. Comparison of Open Channel Flow & Pipe Flow 1) OCF must have a free surface 2) A free surface is subject to atmospheric pressure 3) The driving force is mainly the component of gravity along the flow direction. (e) Minimize the discretion in selecting the canal design parameters and to have uniform practice of canal design on all the projects irrespective of the designer. Using Lagrange’s method of undetermined multipliers, the optimal canal dimensions were obtained for minimum water loss. An artificial water course or extensively modified natural channel used for inland water transport and/or the control and diversion of water for drainage or irrigation Two constraints (minimum permissible velocity as a limit for sedimentation and maximum permissible velocity as a limit for erosion of canal) have been taken into consideration in the canal design procedure.
