DEVELOPMENT OF AN EMPERICAL EQUATION FOR COMPUTING PRESSURE LOSS OF FOOT VALUES IN PUMP SETS.

Abstract

Out of total loss of pressure in a pump, foot valve alone contributes 10% to 15% of the loss. However, with improved foot valves, it is possible to reduce this loss considerably. This paper reports about different shapes of foot valves (such as cylindrical, conical and hemispherical) having enhanced values of dome surface area and strainer opening area. Based on experiments and dimensional analysis, an emperical equation has been obtained to quantify the pressure loss in foot value for design and operation purposes.
