If you want to know how to optimize the inner diameter of the segmented pipe (saving money!) The first section of pipe D=25 mm, the total length of Lt=100 m PE plastic pipe, the second section of pipe length L2=30 m, pipe diameter D2=20 mm, the third section of pipe length L3=30 m, pipe diameter D3=16 mm, micro nozzle spacing L=3 m, nozzle flow rate Qd (l/h)=50, its head loss is hf (m)~ position X (m) relation curve to see if it is in the area of a suitable pipe. You can change the pipeline parameters and then perform calculations. After entering the data, click [Calculate].

Note: Q= *** is the flow through the pipe section, → the front is the velocity. At the water inlet, the flow at X=0 can be used to calculate the design flow of the lateral pipe.
