What is one common cause of pulsation in fluid systems?

Pulsation in fluid systems often arises from rapid changes in flow rate. When the flow rate fluctuates dramatically, it can create pressure variations and momentum changes within the system. This leads to the phenomenon of pulsation, which is characterized by an oscillating flow or pressure pattern.

Such rapid changes can occur due to various factors, including the operation of pumps, valves rapidly opening or closing, or changes in system demand. These dynamics disrupt the steady flow of fluid, resulting in oscillations that can affect the performance and integrity of components within the system.

In contrast, consistent pressure throughout the system, stable temperature control, and excessive filtration do not typically contribute to pulsation. Instead, they help maintain steady state conditions which are essential for smooth operation in fluid systems.
