Critical pressure in a nozzle is the pressure at which the flow of material through the nozzle reaches its maximum. Beyond which any increase in pressure will not result in an increase in flow. The point at which the velocity of a fluid in the throat of the nozzle reaches the local speed of sound, creating a sonic wave, or a sonic choke.

Why is nozzle control governing not employed a reaction turbine?
in reaction turbine pressure compounding is employed as every stage has a set of nozzle ring nozzle control is not feasible.
Why Fluid Speed Increases in the Divergent Portion of a Convergent-Divergent nozzle?
Because the fluid is allowed to expand in the nozzle it increases velocity to fill in the voids created by the shape of the nozzle. The convergent point of the nozzle acts like a bottleneck trying to slow the fluid and compress it into the reduced crosssection of the nozzle. As it leaves the minimum crosssection it expands into the divergent spaces of the nozzle increasing in velocity as it expands. ++_+ No: it gains velocity through the convergence but in the diverging section, trades velocity for pressure.
what is purpose of nozzle in steam turbine?
It sends hot gases from the combustion chamber to the 1st stage turbine blades at the correct angle and speed
What is the nozzle coefficient of a bit nozzle?
0.42
How does a wedco model 40730 nozzle work?
The Wedco Nozzle is a CARB compliant spill-proof gas can nozzle. With the nozzle in place you can invert your gas can and it will not leak. Then simply push the nozzle lock and push the nozzle against the rim of the filling throat of the tank you're filling to start the flow of fuel. If you lift the nozzle away from the rim the flow stops.
Why does pressure drops in a nozzle?
Pressure drops in a nozzle due to the conversion of potential energy into kinetic energy as the fluid accelerates through the nozzle. This decrease in pressure is necessary for the fluid to reach a higher velocity.
How do you calculate the exit pressure of a nozzle?
How to calculate the ratio of the inlet-to-exit area of the nozzle
What is nozzle pressure?
Pressure build up due to restricted orifice.
What is the best way to adjust the water pressure nozzle for optimal performance?
To adjust the water pressure nozzle for optimal performance, start by turning the nozzle to the lowest pressure setting and gradually increase it until you reach the desired pressure. Experiment with different settings to find the best pressure for your specific cleaning needs.
What are the benefits of using a high pressure nozzle for a pressure washer?
Using a high pressure nozzle for a pressure washer provides more powerful cleaning, faster results, and better efficiency compared to lower pressure nozzles.
How do you adjust the nozzle opening pressure of injector on diesel engines?
by rotating the ring which cover the opening of the nozzle
Why do rockets have a Diverging Nozzle at the exit?
To increase the exhaust velocity. +++ Pressure, not velocity. A gas flowing through a divergent nozzle gains pressure at the cost of speed.
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.
What is use of jet nozzle?
To increase thrust or pressure
What are the best maintenance tips for a high pressure washer nozzle?
To maintain a high pressure washer nozzle, regularly clean it with water and a soft brush to remove debris. Check for any clogs or damage, and replace the nozzle if necessary. Store the nozzle in a dry place when not in use to prevent corrosion.
Why is nozzle control governing not employed a reaction turbine?
in reaction turbine pressure compounding is employed as every stage has a set of nozzle ring nozzle control is not feasible.
Why can you only get 3 or 4 gals of gas in tank before nozzle trips?
Generally this happens because of the amount of gas flowing from the nozzle. The nozzle "trips" due to back pressure. When the tank is full, gas pushes back on the nozzle and it shuts off. If the amount of fuel coming out of the nozzle fills up the filler tube going to your tank it also will cause back pressure and shut off the nozzle.
