Bernoulli's principle is a key concept in fluid dynamics that relates pressure, speed and height. Bernoulli's principle states that an increase in the speed of a parcel of fluid occurs simultaneously with a decrease in either the pressure or the height above a datum.The principle is named after the...

Fluid Flow Applications and Conservation Principles: Understanding Bernoulli's Equation
Bernoulli's equation is a fundamental principle in fluid dynamics that explains the
relationship between pressure, velocity, and elevation in a fluid flow.
Bernoulli's principle states that as the velocity of a fluid increases, the pressure
within the fluid decreases.
This principle is based on the conservation of energy and is derived from the
principle of conservation of mass and the principle of conservation of energy.
Device Measurement and Flow Analysis: Pitot-Static Tube, Venturi Meter, and Beer Keg Examples
Pitot-Static Tube:
A Pitot-static tube is a device used to measure the velocity of a fluid flow by
measuring the pressure difference between total pressure and static pressure.
It is used in applications such as aircraft to measure airspeed.
Venturi Meter:
A Venturi meter is a device used to measure the flow rate of a fluid by measuring the
pressure difference between the upstream and downstream sections of the meter.
It is used in applications such as water supply systems and industrial processes.
Beer Keg Examples:
The principles of Bernoulli's equation and fluid dynamics can be illustrated using a
simple beer keg with a small hole in the side.
As the beer is poured out of the keg, a decrease in pressure is observed near the
hole due to the increase in velocity of the beer flowing out of the hole.
