Bernoulli's Principle

Definition

Bernoulli's Principle states that in a flowing fluid, an increase in the fluid's velocity occurs simultaneously with a decrease in pressure or potential energy. This principle is fundamental in understanding how fluids behave in various systems, including geothermal systems where fluid dynamics play a critical role in energy extraction and transfer.
