Why would you not heat the steam coming out of turbine and feedback to turbine?
becouse this steam is use repetdly for the turbine
What materials are needed to build a wind turbine?
The materials that are needed to build a wind turbine are quite basic. You need some PVC sheets, glue (*preferably white*), screws, washers, dowels, magnets, and wire. Its quite simple. ADDED: Note the question does not cover application, just the turbine, though that answer seems to assume it is to rotate an electrical generator. It would also help to have at least some understanding of how to design turbines (and alternators?), and then the tools and skills to cut, shape and join those materials to obtain the desired result. Good Luck though - it would be an interesting, and if successful, satisfying project!
Why use journal bearing in turbine?
putting a journal bearing at each end of the turbine rotor or shaft would be to support it.
How do you can control water turbine?
Well Really It Would Depend On What Type Of Water Turbine You HAd Yuo Should Contact The Manufacturer.
What is the effect of silica on steam turbine blades?
Although several factors influence the formation of deposits on turbine components, the general effect is the same no matter what the cause. Adherent deposits form in the steam passage, distorting the original shape of turbine nozzles and blades. These deposits, often rough or uneven at the surface, increase resistance to the flow of steam. Distortion of steam passages alters steam velocities and pressure drops, reducing the capacity and efficiency of the turbine. Where conditions are severe, deposits can cause excessive rotor thrust. Uneven deposition can unbalance the turbine rotor, causing vibration problems.The nature of silica deposits found on turbine blades varies greatly. lists a number of silica compounds that have been identified in various studies of turbine blade deposition. Of these, amorphous silica (SiO2) is the most prevalent.Localized Silica Saturation. Turbine deposits are also formed where localized silica saturation occurs and silica condenses from the steam in those areas of the turbine. Partial evaporation of the precipitated silica can then occur with only a portion of the silica being dissolved by the continuous steam flow. Deposits remain as a result.Turbine Velocity. Another factor affecting the location of turbine deposits is the velocity in the turbine. Steam flows from the inlet to the outlet of the turbine in only a fraction of a second. Consequently, deposition is shifted downstream from the saturation point by the high steam velocities.Prevention of Silica DepositsThe most significant factor in minimizing turbine silica deposits is the maintenance of low silica concentrations in the boiler water. External treatment equipment must be operated carefully to limit the amount of silica entering with the makeup water, and the condensate must be monitored to minimize contamination. After silica enters the boiler water, the usual corrective action is to increase boiler blowdown (to decrease the boiler water silica to acceptable levels) and then to correct the condition that caused the silica contamination.
What kinds of materials would make good turbine blades?

How long and how thick are wind turbine blades?
Wind turbines blades are about 15 meters long (average wind turbine) The thickness of the blade depends on the length of the blade. The width is about 10% of the length, in this case, would be about 1.5 meters thick.
Do wind turbines take energy out of air?
No. But the probably take energy out of wind. Turbine blades use the effect of drag to produce the energy, so the blades must slow down the wind somewhat. Although it would probably be to small of amount to measure.
Why birds hit onaeroplane would be disastrous?
One example would be :-if the bird was of substantial size the impact of a bird in an aeroplanes turbine system would result in a few instances as follows- the impact of the birds flight path, speed and direction multiplied by the planes flight path, speed and direction could result in the turbine blades becoming damaged and bent off of the axles axis which would result in the blades being forces through the surrounding sheetmetal causing shards of metal and debree that would cause the engine to explode and potentially destroy that said wing entirely.- another possibility would be the impact could throw the propeller turbine blades into the surrounding sheetmetal and cause a "Frozen" effect on the turbine locking them into place, which would lock down the engine and could not propell the plane forward and would either cause the plane to go into a spin as one engine will be working one not, another would be the plane will lose altitude and need an emergency landing to be made, or the sudden lock up of the turbine would cause the engine to ignite due to inscreased pressure and heat and fuel lines would ignite either taking the wing with an explosion or the whole plan in the same instance.these are worst case scenario's of course as many planes will receive no damage from birds in the turbine blades as some are designed with some minimal debree in mind to function as intended.hope this helps with your question.-Cheers
Would a turbine be a chemical or physical change?
Turbine is not a change, a turbine is a mechanical device.

"How do you make a Wind Turbine model"?
This would sound very complicated for me. I actually find projects boring. The materials to construct a Wind Turbine model is cardboards, glue, ruler, scissor, pencil, insulation tape, safety pins and decorations(personal preferences). I find this project hard to do, but other's think it's fun. I only know the materials, but not the steps.
Why would a turbine be used instead of a water wheel?
a turbine would be used instead of a water wheel because a turbine does not use as much energy and it uses the wind to generate it.
How much does a small steam turbine cost?
That would depend on the type and size of turbine.
What teeth did the native Americans use for knife blades?
Native Americans used a variety of materials for making knife blades, depending on the resources available to them in their specific region and time period. Some of the materials commonly used by Native Americans for making knife blades include: Stone: One of the earliest materials used for making knife blades by Native Americans was stone. They would shape stones such as flint, obsidian, chert, and quartz into sharp edges by knapping or flaking techniques. These stone blades were used for cutting, slicing, and butchering. Bone: Native Americans also used animal bones, such as deer antlers, to make knife blades. They would shape the bones into sharp points or edges by carving, grinding, or polishing. Bone blades were commonly used for cutting, scraping, and carving tasks. Antler: In addition to bones, Native Americans utilized antlers from deer, elk, and other animals to make knife blades. Antler blades were often shaped into sharp points or edges and were used for cutting, slicing, and hunting. Shell: Some Native American cultures used shells, such as abalone or clam shells, to make knife blades. They would shape the shells into sharp edges by grinding or polishing techniques. Shell blades were used for cutting, scraping, and carving tasks. Copper: In certain regions where copper was available, Native Americans used copper to make knife blades. They would hammer and shape the copper into sharp edges, which were then attached to handles made from wood or bone. Copper blades were used for cutting, slicing, and ceremonial purposes. Obsidian: Obsidian, a naturally occurring volcanic glass, was highly prized by Native Americans for making sharp and durable knife blades. Obsidian blades were formed by carefully flaking and shaping the glass into sharp edges. They were used for cutting, slicing, and ceremonial purposes. Overall, Native Americans were resourceful and skilled at utilizing natural materials to create effective knife blades for various tasks and purposes. The specific materials used for knife blades varied depending on geographic location, cultural traditions, and availability of resources.
