👉 The laws of fluid, also known as fluid dynamics, describe the behavior and motion of fluids—liquids and gases—under various conditions. These laws encompass principles such as conservation of mass, which states that the amount of fluid entering a system equals the amount leaving plus any accumulation; conservation of momentum, which explains how forces affect fluid flow; and Bernoulli's principle, which relates the speed of a fluid to its pressure, indicating that faster-moving fluids have lower pressure. Additionally, the Navier-Stokes equations mathematically model fluid motion, accounting for factors like viscosity, density, and external forces. Together, these laws govern everything from the flow of water in pipes to the aerodynamics of aircraft wings.
