Transient analysis for large rising mains is performed to protect them from worst effects of water hammer. It requires costly surge analysis software for analysing system for surge & sizing surge protection devices. If software is not available, engineers requires, selection charts or formulae pertaining to quick sizing of surge protection device for given pumping main. If size of surge protection device is known suitable cost shall be considered in budgetary estimates. Surge anticipating valve is a cost effective, compact & reliable surge protection device used in pumping mains. It is installed on delivery manifold of the pump. There are no design guidelines or selection charts available by valve manufacturers for selection of surge anticipating valves. Hence in this paper, charts are prepared to estimate amount of surge & size of surge anticipating valve using KYPIPE TranSurge software after numerous analysis of pumping mains for various combinations of flows, diameters, elevations and lengths. In the end, software results are validated by comparing it with results obtained by experiment.
