What are the advantages and disadvantages of flow nozzle?
One disadvantage in the convergent-divergent nozzle as a shock wave can take place in the nozzle A nozzle is a device that converts pressure energy to kinetic energy (increasing fluid velocity on the account of static pressure) For a convergent nozzle there is no disadvantages as it can raise the fluid velocity only for the sonic speed the convergent-divergent type raises the velocity to over than sonic speed making supersonic flow, this could make a shock wave in the nozzle that turns the supersonic flow to subsonic flow
What is the conditions of steam velocity while flow through steam nozzle?
Nozzles are designed to increase the steam velocity.
What is the difference between divergent nozzle and diffuser?
too bad i dont know what either of those are
What is a swirl nozzle?
Spiral nozzle is a full or hollow cone spray nozzle,jet angle range can be 30°-180°.flow rates range from 5.5 to 4140 l/min.Spiral nozzle has NPT or BSPT external thread type. Usually 1/4 inch to 6 inch nozzle can be used brass, SS304, 303, 316, 316L materials , as spiral nozzle factory, we sell and manufactuer mutli spiral nozzles.

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.
The spelling of nozel or nosel?
The correct spelling is "nozzle." A nozzle is a projecting spout or fixture designed to control the direction or flow of a substance, such as in a hose or pipe.

What is nozzle contraction ratio?
Ratio of the cross-sectional area for gas flow at the nozzle inlet to that at the throat.
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.
What does the the nozzle do on a Bunsen burner?
The nozzle that the burner tubing connects to allows gas to enter into the burner. Also, the nozzle has a lever that allows you to control how much gas will flow into the burner.
What is the maximum water flow through a 3 inch fire hose?
To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
How does the service stations pumps sense when the fuel in the vehicles tank is full and click off automatically?
If you look at the end you will see that there is a small tube inside. As long as it is 'pulling' vapor from the end of the nozzle, the gas flows. When it gets liquid in it, it turns the flow off. If there is a splash into the nozzle, it will cut out early.
How can you power a toy car with water?
with pressure , valve and a nozzle , yes water to a tank, pressurize it flow to a vlalve and out through a nozzle will cause forward thrust
How is supersonic flow produced in a de laval nozzle?
Supersonic flow is produced in a de laval nozzle by constricting the flow in the center in order to increase the velocity. The shape will be hour-glass in nature. The initial mass flow rate and inlet pressure must be sufficient to produce a supersonic choked flow and the discharge pressure must be sufficiently low enough for supersonic flow to occur.
How do you use fire hose?
A fire hose is used to transfer water. It is generally connected to a pump (which is connected to a water source), and has a nozzle on the other end. When the valve to which the hose is connected is opened (with the pump running), water will flow down the length of the hose to the nozzle. The firefighter will direct the nozzle where he wishes the water to go, and will open the gate on the nozzle. As water sprays onto the fire, the firefighter will actively direct the stream or spray to most effectively extinguish the blaze. We also see fire hose used to connect two or more pieces of equipment. If a large fire requires a truck to apply water, the truck will set up close to the fire, and fire hose will be laid to an engine. This allows the engine , which is connected to a water source, to pump that water to the truck.
Does a fire in a fireplace burn better when the outdoor air is calm or windy?
The fire in a fireplace burns well when it is drawing well, which means it is getting a steady flow of fresh air (& oxygen) to the fire and exhaust/smoke is flowing steadily away. An open fireplace in a building needs quite a large volume air to be supplied to it (either from a draughty or well ventilated room, or through a vent), and a large exhaust through the chimney. The wind around the building can affect the drawing of the chimney by creating high and low pressure areas. If the chimney top is in a lower pressure area than the room with the fireplace, the air will draw steadily through the fireplace and chimney, because air in a high pressure zone will want to flow to a lower pressure zone. If the chimney top is in a higher pressure area than the room, the flow will tend into the room, bringing the smoke with it. Wind direction and speed can affect this, as can the position of the chimney opening and the ventilation of the fireplace room. A well designed fireplace should draw well in all wind strengths and directions, but many do not.
