This will get you within a pipe size of the "correct" answer. For old rusty pipes k s 1 – 3 mm and for new zinc-plated pipes 0. Enter the pump flow rate and press the AUTOSIZE button. ; it includes the water distributing pipes, control devices, equipment, and other appurtenances. Short samples of each size test pipe (24) are provided loose so that you can measure the exact diameter and determine the nature of the internal finish. Diameter factor that you have mentioned in head loss equation will be compensated by the flow rate (Q) or Velocity(V) in the numerator. But for lower sizes the OD calculation is not so easy. 1) If the pipe always operates under normal open channel flow (Manning's flow), you can model it as a separate pipe reach. pipe is relatively smooth compared to corrugated metal pipe, it has good hydraulic characteristics, permitting more water to flow through a given size than can pass through corrugated metal pipe of the same size. It outputs the flow type you can expect (laminar, transitional, or turbulent) based on the Reynolds Number result. Yes if the water is going in the same direction and has joining flow to a pipe at lease 11/2 times the diameter of one of the two equal pipe ( two 1 " pipes should join a 11/2 "pipe ) sizes joining a T on the stem and one side at the top going out. This calculator shows the relationship between the K value and pipe length. So if you look up 2", you'd see 3300gph through 100' of 2" pipe if just flowed by gravity. The black system curve is composed of a static head of 47’ and the friction head produced by 300’ of 6” steel pipe.
