Abstract

                                Foot valve is an important component of a pump set. For the loss of pressure in a pump, foot valve is responsible for 10 to 15 percent of the loss. However, with improved foot valves, it is possible to reduce this loss considerably and save energy consumption. By experiments and dimensional analysis, it is clearly indicated that the lesser strainer opening ratio increases the head loss and vice-versa.

Key words : Pump sets, Foot valves. Strainer Opening ratio, Head loss.
