I tried to answer this question 4 times but WikiAnswers won't accept the code word to submit it, even though it is correct all 4 times. Converging / diverging nozzles are used with compressible fluids (gases, including steam) to increase their velocity. The converging section (cross-sectional area decreasing in the direction of flow) increases the velocity until it reaches the velocity of sound in the gas (sonic velocity - "Mach 1"). At that point, further reduction in area would slow the gas down, but increasing the cross-sectional area in the direction of further flow allows the gas to expand and increase its velocity to supersonic. If you only had a converging nozzle the maximum speed of the gas could only be subsonic or sonic. The diverging portion of the nozzle needs to be added to achieve supersonic speeds. The converging-diverging nozzle (also known as DeLaval nozzle) is used in steam turbines, most if not all rocket engines and all supersonic wind tunnels.

Actually, gas flowing though a diverging nozzle LOSES velocity but gains pressure, and it is pressure in the impinging stream the turbine needs, not its velocity.
What else can I help you with?
Cleaning Basement mold?
Pressure washing can be a fast way of removing mold and algae build up. Use a surface cleaner from best car gurus to do it multiple times faster than a regular nozzle
Can you use propane gas with natural gas logs why not?
No, it is not recommended to use propane gas with natural gas logs because they are designed for different types of gas. Propane and natural gas burn at different rates and temperatures, so using the wrong type of gas can be dangerous and can result in incomplete combustion. It is important to always use the type of gas that the appliance is designed for.
Why does the stream of water travel farther when less water is flowing from the end of the hose?
When using a high pressure pump, you'll find that a smaller output nozzle gives *shorter* spray than a large nozzle. Small nozzles limit the flow. Yet with a garden hose things are reversed. Why? It's because the long narrow hose and the pipes connecting it are acting like "friction." If you turn on the water, the hose rubs against the wate, and water flows relatively slowly out the end of the hose. Also, the water pressure at the open end of the hose is very low. Now install a garden sprayer at the hose end. This will greatly slow down the water flow, and the effect of friction is greatly reduced. The pressure at the far end of the hose rises, and this high pressure can create a very long (but narrow) spray. Another way to explain is with numbers. The greater the fluid resistance is to a constant flow, the greater the pressure-difference must be across that resistance. The fluid resistance value of the hose is large, while the resistance value of the hose-end is small, and since the same flow goes through both the hose and through its end-opening, most of the pressure-difference appears along the hose, while very little pressure-difference appears between the hose and its opening. Now install a very narrow opening. If the fluid resistance of this nozzle is the same as the fluid resistance of the hose, then half of the faucet pressure appears along the hose, while the other half appears between the hose-end and the outside world. The nozzle has increased the pressure at the hose end. And if the fluid resistance value of the nozzle is much greater than that of the hose, then nearly all of the faucet pressure will appear at the nozzle. So, to produce a long jet of water, use a very wide hose and a very narrow nozzle. Or even better, entirely get rid of the resistance created by the hose, and connect the nozzle directly to a high pressure water pump.
What type of lens are used in telescope?
Telescopes typically use convex lenses (also called objective lenses) to gather and focus light from distant objects. These lenses help magnify the images and make distant objects appear closer and more detailed. Eyepieces with different magnifications are then used to further enhance the view.
How can avoid stucking hot tube together?
To prevent a hot glue tube from becoming stuck, always recap the tube securely after use and store it in a cool, dry place. Try to avoid leaving the tube lying flat after using it, as this can cause the glue to dry around the cap and nozzle, making it difficult to open. If the tube does become stuck, soaking it in warm, soapy water can help loosen the dried glue and make it easier to open.
Does a camera use a diverging lens?
All cameras have converging lenses instead of diverging because they need a real image and not a virtual one to capture a photo.
What is another name for a convex lens?
Concave and convex can refer the types of lenses used to treat refractive errors in the eyes. Concave is another word for myopic lens and convex is another name for a hyperopic lens also known as nearsighted and farsighted respectively
How are nearsightedness and farsightedness corrected?
We use corrective lenses in spectacles. Near sight is corrected with diverging lenses and far sightedness with converging lenses.
Do guns use a converging-diverging nozzle to accelerate bullets to supersonic speeds?
No, bullets are accelerated by rapidly expanding gasses. Those gasses are in a cylinder only open at one end. The bullet acts as a piston, and is pushed out of the open end of the cylinder. Not all bullets are supersonic, but those that are become supersonic from the amount of acceleration, and the time it is applied.
WHY would it not be a good idea to use a diverging mirror instead?
Using a diverging mirror instead of a converging mirror in optical systems would not be a good idea because a diverging mirror spreads out light rays causing them to diverge, resulting in a virtual and diminished image rather than a real and magnified image. This would not be suitable for applications where a focused and enlarged image is desired.
Why do we use concave mirror as converging mirror?
why do we use concave mirror as converging mirror
Which lens is a converging lens a double-convex lens or a spherical-convex lens or a plano-concave lens or a convexo-concave lens?
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
Why diverging lens cannot be used as magnifying glass?
a diverging lens can not be used as a magnifying glass becuase a diverging lens( concave) lens diverges the the rays cousing the image to not be erect, but upside down. While magnifying glass ( convex) is used as it is a converging lens which focuses the rays in one point of an objects making it magnifies and erect.( right way up)
