Water Hammer formulas and calculations

This Excel sheet presents all formulas and calculations needed for water hammer and pressure surge including water velocity, wave time, maximum pressure, time, and resulting friction loss.

What is Water Hammer ? What does 'Water Hammer' mean?

Water Hammer is a pressure surge or wave that occurs when there is a sudden momentum change of a fluid within an enclosed pipeline system. This commonly occurs in pipelines when a valve is closed suddenly at the end of a pipeline where the velocity of the fluid is high.
