the water is flowing through a velocity of 1.5m/s in a pipe

the water is flowing through a velocity of 1.5m/s in a pipe of length 2500m and dia 500mm. at the end of pipe a valve is provided. find rise in pressure 1. if the valve is closed in 5 seconds. 2. if the valve is closed instantaneously. take value of c = 1460m/s, pipe to be rigid and bulk modulus of water 19.692x10' n[pipe]The Manning Equation Relates Stormwater Flow Velocity in a [hdpe]The Manning equation is very useful in storm sewer hydraulic design calculations. It gives a relationship among stormwater flow velocity, pipe roughness coefficient, and storm sewer diameter and slope. For a circular storm sewer flowing full with stormwater, the hydraulic radius is equal to one fourth the diameter. This simplifies the Manning equation, making the desired calculations fairly easy.[pipe]Pipes & Pipelines Technical Resources and Information [hdpe]Vinidex technical information is drawn from worldwide research and field experience with advanced pipes and fittings systems and technology.
