Cadmans Friction Loss Calculator which calculates the amount of friction or pressure lost through any standard irrigation system setup. The user enters their specific variables pertaining to their system - pipe, hose or tube length, the coefficient which represents the material or the pipe, hose or tubing; flow rate, i.e. GPM (gallons per minute); and the internal diameter of the pipe itself. Future updates will include a Cadman news feed, product gallery, access to Cadman catalogues and other product related information.
