Calculation of Water Hammer Pressure Due to Valve Closure
The objective of this study was to compute the pressure increase in a pipeline generated by closing a valve. The specific problem to be considered herein was the closure of a downstream valve on a line of length L, bounded by a constant pressure reservoir at the inlet. A terminal valve was closed in a prescribed but arbitrary manner over a period of time. The pressure increase at the valve, due to the closure, was computed. This simple hydraulic system that occurs commonly in practice can also adequately represent trunk lines attached to a large principal conduit. This paper presents an “exact” solution to the slow valve closure problem in a very simple form. The solution must necessarily consider the particular closure function for the situation being analyzed. The effects of line friction are not considered, but this effect is usually not large. The additional increase in head at the valve over the waterhammer pressure due to line friction is usually given closely by the initial friction loss in the line.
