Irrigation Pipes Size (HUNTER)

The document contains data on the maximum flow rate in pipes of various diameters at different velocities. It shows that as the pipe diameter increases, the maximum flow rate also increases. It also shows that at a given diameter, the maximum flow rate is highest at the highest velocity of 2.0 m/s and lowest at the lowest velocity of 1.0 m/s. Tables with the number of sprinklers needed at different pipe diameters and sprinkler specifications like nozzle type and flow rate are also included.
