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.
Converging nozzles are used to accelerate steam flow by converting pressure energy into kinetic energy, while diverging nozzles help to convert this kinetic energy back into pressure energy, resulting in increased efficiency and power output for the steam turbine. This design allows for optimal steam expansion and energy conversion in the turbine.
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
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.
When less water is flowing from the end of the hose, the velocity of the water increases due to conservation of mass. This higher velocity allows the stream of water to travel farther before gravity and air resistance slow it down.
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.
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.
All cameras have converging lenses instead of diverging because they need a real image and not a virtual one to capture a photo.
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
We use corrective lenses in spectacles. Near sight is corrected with diverging lenses and far sightedness with converging lenses.
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.
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
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.
Diverging lenses spread light rays apart, causing the image to appear smaller and virtual. This makes it unsuitable for magnifying purposes as it does not converge light rays to create a larger, real image. Magnifying glasses use converging lenses to magnify objects by bending light rays towards each other to create a larger, real image.
