Bernoulli’s principle, formulated by Daniel Bernoulli, is a fundamental concept in fluid dynamics. It relates pressure, speed, and height within a fluid. Here are the key points about Bernoulli’s principle:
Statement of Bernoulli’s Principle:
As the speed of a moving fluid (whether liquid or gas) increases, the pressure within the fluid decreases.
Simultaneously, an increase in fluid speed corresponds to a decrease in static pressure or the fluid’s potential energy.
Conservation of Energy:
Bernoulli’s principle can be derived from the principle of conservation of energy.
In a steady flow, the sum of all forms of energy (kinetic energy, potential energy, and internal energy) in a fluid remains constant at points free of viscous forces.
