By Bernoulli's principle velocity head x pressure head is always constant

So as velocity increases at the nozzle the pressure falls down automatically.

What is the effect of friction on the flow through a steam nozzle?

Friction in a steam nozzle can result in energy losses, reducing the efficiency of the nozzle. Frictional forces can cause pressure drops and decrease the velocity of the steam flow, impacting the overall performance of the system. Proper design and maintenance are essential to minimize frictional losses in steam nozzles.


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 the difference between Diffuser and nozzle?

A nozzle is a device which increases the velocity of fluid by decreasing the Pressure but contrary to it Diffuser is a device that increases the Pressure of fluid at the expense of its velocity


Why does air rush into a vacuum cleaner nozzle?

To understand why air rushes into a vacuum cleaner nozzle we need to trace air flow in the machine. Let's do that. The motor in a vacuum cleaner spins a fan, and the fan moves air. The air intake for the fan is connected to ducting that is routed to the nozzle. As the fan forces air out in its exhaust stream, it creates low pressure on the suction side of the fan. This low pressure (a partial vacuum) is felt along the air path to the nozzle. At the nozzle, outside air pressure forces air into the ducting where air pressure is lower. The moving air has picked up debris and carries it along. That debris ends up in a bag or filtered dirt canister or someplace else where it can accumulate and be collected for disposal. This applies to machines that have bags or filters to get the debris out of the air stream before it goes through the motor to keep it cool. Some machines isolate the motor from the air stream created by the fan, and the motor is cooled by another fan. These "direct" vacuums operate in a way that sees the air stream and the debris pass through the fan and be driven into a bag. The operation of the fan has created a low pressure area along the ducting between it (the fan) and the nozzle. Outside air pressure, being greater than the low pressure created by the fan and ducted to the nozzle, forces air into the nozzle.


How can expansion take place when steam pass through a nozzle?

When steam passes through a nozzle, it undergoes adiabatic expansion due to the decrease in pressure. This expansion causes the steam to increase in velocity as it exits the nozzle, converting some of its internal energy into kinetic energy. The increase in velocity results in a decrease in pressure and an increase in velocity, which can be harnessed in devices such as turbines.

What is critical pressure in nozzle?

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.
