What is the simplified expression for the increase in pressure caused by hydraulic shock?

The Jacowsky Formula specifically addresses the phenomenon of hydraulic shock, commonly known as water hammer. It provides a way to calculate the increase in pressure that results from the sudden change in flow velocity, such as when a valve closes quickly or a pump stops abruptly. This formula is essential for understanding and predicting the pressures exerted on the piping system during transient events.

In contrast, Bernoulli's Principle describes the relationship between pressure and velocity in a flowing fluid but does not directly quantify the effects of rapid changes in flow resulting in hydraulic shock. The Euler Equation is used to describe fluid motion and can help in broader fluid dynamics but is not explicit for hydraulic shock situations. Similarly, the Darcy-Weisbach Equation is focused on calculating pressure loss due to friction within pipes and does not apply specifically to transient conditions like hydraulic shock. Thus, the Jacowsky Formula stands out as the correct choice for determining the increase in pressure associated with hydraulic shock.
