• ### Pumping Head Height Explained | Creative Pumps

2021-5-14 · Pumping water through tubing adds resistance, so an allowance must be made for friction loss inside the tube. As a rule of thumb add 10cm of head for every 1 meter of horizontal tubing run. However as the size of the tubing has a significant bearing on frictional resistance, the use of an undersize tube will increase frictional losses.
