  Hydraulic Hammer

Version 18.0 - October 2019

This program calculates the water hammer caused by slow closing of a valve downstream. The water level of the tank is assumed constant. For the friction calculation, one of 15 available formulas may be used. The solver is based on the method of characteristic lines which substitutes the hyperbolic partial differential equations with common ones. The program can show the variation of the pressure, celerity and flow rate along the pipe in a visual and animated way, including the maximum over-pressure and sub-pressure. Alternatively, the results can be displayed in tabulated form.
