Water Pipe Sizing Chart12.3
Don’t cheat yourself with undersized pipe! Use this
chart to determine the additional head imposed on your
pump due to pipe friction, based on flow rate, pipe size and
pipe length. Consider the TOTAL pipe length from the pump
to the pipe outlet to the tank.
Friction Loss in Plastic Pipe with Standard Inside Diameter (SIDR)Table 11:
Head loss from friction in vertical m/ft per 100 m/ft of pipe.
Pipe fittings impose additional friction loss. A sharp 90°
pipe elbow adds friction approximately equal to 6 ft (2 m)
of pipe of the same size.
This chart applies only to PVC pipes,
schedule 40 (160 PSI), and to
polyethylene (PE) pipes with SIDR
designation (most common 100 PSI
black flexible pipe).
Shaded values are velocities over 5 ft
per second and should be avoided.
Choose a larger pipe diameter.
*) 1/2 in data applies to polyethylene pipes only. PVC pipes have a smaller ID of 0.612 in.
