Water hammer and Corrigan's pulses [PDF]

Clinical Case Reports, 2022
Abstract Corrigan’s pulse is characterized by the abrupt distension and quick collapse of carotid arteries in aortic regurgitation, whereas water hammer pulse is the characteristic pulse observed in peripheral arteries.

Analysis and research on water hammer protection measures based on KY PIPE for long distance pumping station water transmission engineering with pump stoppage [PDF]

Scientific Reports
In the process of long-distance pressurized pipeline water transmission, in addition to the problem of water hammer hazards that can easily occur in the pipeline, the safety of the pipeline before the pump also presents hidden dangers.

Water Hammer

Surge pressure, closure time, and the valve nobody timed A pressure rating is a statement about a pipe standing still, and a transient is a wave that arrives and leaves before the rating has any way to respond. Surge pressure is produced by a change in velocity over a time, and the only time that matters is the one measured against the pipe's own ...

Effects of water-hammer impacts on aspirated pits and tyloses, liquid permeation, and collapse of wood

Journal of Wood Science
This paper deals with a water-hammer impregnation method previously developed as a novel approach to improve the uniformity of liquid impregnation into wood, by targeting aspirated pits and tyloses, which are known to restrict liquid flow.
