Bernoulli's principle only applies when no work is done. Bernoulli principle is approximated if a small amount of work is performed. The cause or the acceleration of air needs to be known before a relationship between velocity and pressure can be established. In the case of the pump, the hole performs a small amount of work on the air, resisting the flow and requiring a higher pressure inside the tube to compensate, but the pressure still drops below ambient as the air accelerates into the hole.LURCH said:When air (or any fluid) moves "sideways" across a surface, it generates less pressure against that surface than air that is sitting still. It is basically an application of Bernoulli's Principle, which states that as the velocity of flow in a fluid increases, the pressure in that fluid decreases.
Yes.Jeff Reid said:I assume that when used, the cannister is below the nozzle as shown in the picture?
Very small, same as that on the cannister.Jeff Reid said:How narrow is the opening in the tube at the end of the pump part?
To kill bugs.Jeff Reid said:What is this sprayer used for?
The high speed air breaks up the fluid into small droplets, and this is called atomizing. Because the air flow is decelerating (moving from lower to higher pressure area) it should be turbulent which should help. Also the air flow of these is designed to spread out as opposed to staying in a narrow stream. All of these factors will help spread out the fluid droplets into a larger area.x3qt0r said:But am still not getting the "atomizing part".

The fluid itself has the quality of easily being dispersed into spray. What happens if you pump very slowly? If you block the flow from the nozzle out of the pump, how fast does the air stream feel?x3qt0r said:Why does that happen.Because even when i blow the plunger slowly there is still amount of spray.
A pump is a mechanical device that is used to move fluids from one location to another. It works by creating a pressure difference, which causes the fluid to flow from an area of higher pressure to an area of lower pressure.
A pump works by using a source of energy, such as electricity or an engine, to power a mechanism that creates the pressure difference. This can be achieved through the use of pistons, impellers, or other types of rotating or reciprocating parts.
There are several different types of pumps, including centrifugal pumps, positive displacement pumps, and jet pumps. Each type has its own unique design and method of operation, which makes them suitable for different applications and fluid types.
The type of pump you need will depend on the specific application and the properties of the fluid being pumped. Factors to consider include flow rate, pressure, viscosity, and temperature. It is best to consult with a pump expert to determine the most suitable pump for your needs.
Pumps are used in a wide variety of industries and applications, including water and sewage treatment, oil and gas production, food and beverage processing, and agriculture. They are also commonly used in household appliances, such as washing machines and dishwashers.
