  Water Hammer Surge Analysis | Fluid Mechanics Ltd

  Water hammer is part of the larger subject of transient flow or surge analysis. It is the special case when there is a sudden change in flow velocity. Usually this occurs when a valve closes quickly. Water hammer can generate very high pressure transients which could burst a pipe and can generate pipeline vibrations. The magnitude of the water hammer pressure rise can be calculated using the ...

  December 2011 | Excel Calculations

  Water Hammer in Excel. This Excel spreadsheet will calculate the maximum pressure surge when the valve at the end of a pipeline is closed. When flow is suddenly stopped, flow inertia causes a pressure surge at the valve, with a shockwave propagating through the pipeline. This is also known as Water Hammer and can cause considerable damage.

  EXPERIMENTAL AND NUMERICAL ANALYSIS OF WATER HAMMER .

  hammer pressure peak is calculated based on the final velocity V f P wh =rcV f being c the speed of sound. Important to mention, the speed of sound is affected by the gas content in the liquid (pressurant gas dissolved in the liquid). In the case of prepressurized line, being the impact velocity zero, the water hammer pressure is the compressed gas pressure P wh =P g(end). .

  Water Hammer Calculation

  Water Hammer Calculation. An abrupt change in the velocity of a flowing liquid in a pipe generates a pressure wave, which is commonly referred as "Water Hammer". This tool was developed using the Joukowsky equation to provide you with a simplified method for calculating the peak transient pressure experienced when a valve is closed against a fluid in motion. Absent a formal surge analysis ...
