  • Head Loss - Pressure Loss | Definition & Calculation ...

    2019-5-22 · Consider that the length of the pipe or channel is doubled, the resulting frictional head loss will double. At constant flow rate and pipe length, the head loss is inversely proportional to the 4th power of diameter (for laminar flow), and thus reducing the pipe diameter by half increases the head loss by a factor of 16. This is a very significant increase in head loss, and shows why larger …

    Head loss in a pumping system increases with increasing flow through the system, and can be shown graphically as a system head curve like that in Fig. 6-15.The system head loss for any flow rate is the sum of friction head loss and the total static head in the system. Static head is present whether the pump is operating or not, and is plotted as the lower portion of the system head curve.
