Introduction of steam nozzles nozzle is a duct by flowing through which the velocity of a fluid increases at the expense of pressure drop. The steamhas a very high velocity at the end of the expansion and the enthalpy decreases as expansion takes place. The flow of steam through nozzles may be takenas adiabatic expansion.

If the fluid is steam then the nozzle is called as steam nozzle. A nozzle is a device designed to control the direction or characteristics of a fluid flow especially to increase velocity as it exits or enters an enclosed chamber or pipe. Steam nozzles powerpoint ppt presentations.

The chief use of nozzle is to produce a jet of steam or gas of high velocity to produce thrust for the propulsion of rocket motors and jet engines and to drive steam or gas turbines.

Heat is produced as the result of the resistance to the flow. Steam nozzle properties of steam can be obtained from tables or from h s chart. The flow of steam through nozzles may be regarded as adiabatic expansion.

If the fluid is steam then the nozzle is called as steam nozzle. The flow of steam through nozzles may be taken as adiabatic expansion. But in order to find the critical pressure ratio critical velocity maximum mass flow rate approximate formulae may be used.
