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.

How long and how thick are wind turbine blades?
Wind turbine blades can range in length from 35 meters to over 80 meters, depending on the turbine's size. The thickness typically varies along the length of the blade, with the base being the thickest at around 20-40 cm and tapering to a thinner edge of 5-10 cm.
Should wind turbine blades be heavy or light?
Wind turbine blades should be light in weight to maximize their efficiency in capturing wind energy. Lighter blades allow for faster rotation speeds with lower wind speeds, resulting in increased energy production. Additionally, lighter blades reduce the stress on the turbine structure and improve overall performance.
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 is hydroelectric form?
Well, how was hydroelectricity formed. First of all people built dams in order to make a reservoir ( man made lake). All the water from the reservoir would then go down the penstock ( a water tube). The penstock would then lead into the turbine ( fan with spinning blades ) . Water would then strike the blade and cause the blade to rotate. The rotating motion would then cause electricity. The generator would guide the turbine through the way. The electricity would then get sent through the power lines.
