ProfessorA diffuser is a device that reduces the velocity of a fluid and increases its pressure, often by expanding the flow area. A nozzle, on the other hand, is a device that accelerates the flow of a fluid by constricting the flow area, which increases its velocity. In simpler terms, a diffuser slows down fluid flow while a nozzle speeds it up.

How do you take of a diffuser from a hair dryer?
First, make sure the hair dryer is unplugged and completely cool. Then, locate the small release button or notch on the diffuser attachment and press or slide it to release the diffuser from the hair dryer nozzle. Finally, gently pull the diffuser off the hair dryer.
What is the difference between HVAC diffuser's neck velocity and face velocity?
Neck velocity refers to the air speed at the neck of the diffuser where the air exits, while face velocity refers to the air speed at the face of the diffuser where air enters. Neck velocity is typically higher than face velocity due to the acceleration of air as it passes through the diffuser.
How current is related to pressure in flapper nozzle?
In a flapper nozzle, the flow rate of the fluid passing through is directly proportional to the difference in pressure across the nozzle. As the pressure increases, the flow rate also increases. This relationship between pressure and flow rate is governed by equations such as Bernoulli's principle and the equation of continuity.
How do you calculate the velocity of nozzle in cylinder?
To calculate the velocity of the nozzle in a cylinder, you need to use the equation of motion, such as the Bernoulli equation. The velocity can be determined by considering the pressure difference between the nozzle exit and the surrounding environment, and the area of the nozzle opening. By applying principles of fluid dynamics, you can calculate the velocity of the fluid expelled from the nozzle.
How do you remove diffuser from fluorescent light?
To remove a diffuser from a fluorescent light fixture, first locate the clips or screws holding it in place. Release the clips or unscrew the fasteners to remove the diffuser carefully. Be cautious not to damage the diffuser or the light fixture during the process.
