What are the objects that use the application of Bernoulli's principle?

Question

Benoulli's Principle science technology

Answer 1

Not enough space to list them all here but Piping Systems, A/C Thermal Expansion Valves, Blades on a Gas Turbine, Venturi Nozzles (Flow Meters), Air Ejectors (in Steam Condensors), Airplane Lift and Control Surfaces, Throttling Valves, Monometers, and Ink Jet Printer Nozzles and the human bladder all use Bernoulli's Principle (BP)

The most prevalant examples of the application of BP is gas and water pipes and systems...every house in the world that has indoor plumbing depends on the convenience of balancing water pressure and water velocity.

The second most prevalant would be the Thermal Expansion valve found in every air conditioner ever made. This TXV uses a restrictor plate to covert high pressure/low velocity freon to low pressure/high velocity. This simple use of BP forces a few of the freon molecules to borrow energy from the pressure and velocity of surronding froen molecules to absorb the needed LHV (Latent Heat of Vaporization) to cool the bulk of the freon. This resulting cooling of the bulk freon is what makes A/C work.

To me the most interesting example is the blades on a gas turbine. The stationary blades acting as nozzles constantly convert pressure into velocity (two terms within the BP). [I am an obsessive fan of avaition and what makes it work.]

And regarding an earlier answer that suggested that BP was not a part of lift and flight is incorrect. Even the site referenced was talking about the very conversions from one type of energy to another type - Flow Energy (Pressure) from Kenetic Energy (speed). Remember that Pressure is just Force/Area...a change in speed (acceleration) causes a force acting over an area (pressure).

You ready for this one?

BP is also the source of function for the human bladder. The conversion of pressure to velocity...maybe not the sexiest application but there it is. Alot of people confuse BP with Pascal's Law (PL). PL simply stated says, "A Pressure felt on a fluid will be felt equally throughout the fluid.". BP, while dependant on fluid pressure goes much further in it's explanation of how fluid energy is transferred, conserved and transmitted. The bladder is the perfect example. A pressure on the fluid, transmitted by the walls of the bladder, throttles through the urethra and even the derivation of the name "pissing" coming from the conversion of flow energy to sound as urine escapes the confines of the urethra. BP at it's best, ya'll.

The apparatus which takes total and full advantage of BP is the venturi nozzle (used to very accurately measure flow rates). The most famous venturi nozzle is the air ejector, used in steam condensors. This sexy, high speed, low-drag version of the Venturi concept does measure fluid flow but rather actually accelerates air to the speed of sound and uses that high velocity steam to suck the life taking air out of vacuum condensors so that steam can be more efficiently condensed at higher temperatures.

Throttling valves, manometers, even the ink nozzles on your inkjet printer have functions covered partly by Bernoulli's Principle.

Answer 2

Bernoulli Principle Application

Answer 3

The airspeed indicator on an airplane. The lift of the wing, however, is NOT due to Bernoulli's principle -- see

for details.

Answer 4

in foundry when molten metal is poured in mould and inter to gate system , we use Bernoulli's principle . but it needs some coeffcient correct.

Answer 5

it is aircrafts,household roofs,venturimeter ,air sprays etc
