What is nozzle and what is diffuser?

A nozzle is a device which accelerates fluid. During this process, velocity of fluid increases with decreasing pressure. A diffuser is a device which slows down fluid. That means, velocity of fluid decreases with increasing pressure.

What is the function of diffuser?

The diffuser is an important element of a compressor or pump. Its purpose is to reduce the velocity of the flow leaving the impeller resulting in an increase in pressure. The diffuser can be simply depicted as a nonrotating channel whose flow area increases in the direction of flow (Figure 7.7).

What is jet nozzle diffuser?

JND Jet Nozzle Diffuser is suitable for supplying cooled and heated air in large areas. Fully adjustable airflow in any direction. Suitable for long-distance air supply. Low noise levels.

What are the various types of nozzles and their functions?

Nozzle

  • Nozzle.
  • The Nozzle Tip is one of the most important and least expensive part of a spraying system. Adjustable nozzle.
  • Double swirl spray nozzle.
  • Selecting a spray nozzle.
  • Hollow cone nozzles-Disc and core type.
  • Flat fan nozzles.
  • Floodjet nozzles.
  • Adjustable nozzles.

What is nozzle and types?

A Nozzle is used to enhance the kinetic energy of a fluid which is flowing at the expense of inertial and pressure energy. Nozzles are of two types: convergent and divergent. Convergent Nozzles are used to accelerate the subsonic fluids while the divergent Nozzles are used to slow the fluids if their flow is subsonic.

What are real life examples of nozzles?

There are following applications of a nozzle are:

  • Nozzles are used in steam turbines, gas turbines, water turbines and in jet engines, Jet propulsion.
  • Nozzles are used for flow measurement e.g. in venturimeter.
  • Nozzles are used to remove air from a condenser.
  • Injectors for pumping feed water to boilers.

How do nozzles and diffusers work?

Nozzles and Diffusers A nozzle is a device that increases the velocity of a fluid at the expense of pressure. A diffuser is a device that increases the pressure of a fluid by slowing it down. The cross sectional area of a nozzle decreases in the flow direction for subsonic flows and increase for supersonic flows.

What is a jet diffuser?

Jet Diffusers are suitable for large spaces or area with high ceilings, such as theatres, concert halls, gymnasiums, mall atriums, exhibition halls, etc. The design of Jet Diffusers allows for a long distance throw along with trajectory control.

What are the three types of nozzles?

Nozzle Description. Nozzle types commonly used in low-pressure agricultural sprayers include flat-fan, flood, raindrop, hollow-cone, full-cone, and others. Special features, or subtypes such as “extended range,” are available for some nozzle types.

How many types of nozzle are there?

There are 5 basic spray pattern types: flat fan, solid stream, full cone, hollow cone and mist/fog. Various nozzle designs are deployed to create these patterns and details on each can be found in the sections below.
