Feet of head is typically measured in terms of vertical lift. However the diameter and length of pipe can have a significant effect on the performance of the pump as well. (Especially if the pipe diameter is too small). A pump must have the power to not only push the water up to the vertical height of the waterfall, but to also overcome the friction loss created by the pipe. In most small ponds, with short pipe runs, friction loss is not typically a problem. However, in a feature with long streams or high flow rates, friction loss can have a big impact on the performance of the pump. To determine the Total Dynamic head you would add the feet of head and the friction loss. The chart lists the feet of head equivalent created by flow and pipe diameter. (Figures shown are based on a 100' length of pipe.) To view the Friction Loss Chart Click on this Link |
