Pressure rise for sudden closure of valve in elastic pipe Formula

pressure = (Velocity of water)*(sqrt(Water Density/((1/Bulk Modulus)+(Diameter of Pipe/(Modulus of Elasticity*(Thickness of pipe))))))
P = (V)*(sqrt(ρWater/((1/K)+(D/(E*(t))))))

What causes high pressure in the pipeline?

Pressure surges during transient operations occur when flow rates are changed in any piping system containing vapors, gasses, liquids, or combinations of these fluids. As valves are opened in pipelines containing pressurized gasses or vapors upstream of those valves, pressure transients occur in the downstream piping.

How do you increase pipe flow?

To change water flow, the opening of a pipe must be adjusted. Changing water pressure is different. To adjust pressure, the diameter or texture of the pipe must be altered using a different regulator/pump or regulator/pump setting.
