To estimate the production of a wind turbine must be given the following factors:
1 - type of wind turbine
2 - wind speed in wind turbine installation
3 - angular velocity of turbine shaft
4 - an area of wind turbine blades that are vacuum
However, using the following formula can be produced by wind turbines can be estimated as:
P = 0.5 * cp * ρ * A * V3
In the formula above:
cp: Power Factor
ρ: air density
A: It is an area of wind turbine that will sweep
V: wind speed
Is.
The turbine can be calculated to consider the following points:
1 - the coefficient function of the ratio of the speed or the speed of EDGE is that it will display with λ, ie:
cp = f (λ)
But λ is a dimensionless number obtained from the following formula:
λ = (Rω) / Vwind
Where:
R = length of wind turbine blades
Vahdsh turbines and ω = angular velocity (rad / s)

∙ 10y agoThere are five steps on how to find the efficiency of the steam boiler. Some of the step-by-step instructions are use the horsepower to calculate steam flow, use the btu/hr heat input rate to calculate boiler steam flow, and calculate boiler steam flow with a known kilowatt hour usage in an electrically heated boiler.

How do you calculate coal usage to produce 1 MW power?
First in order to calculate the heat content of a particular type of coal, an ultimate analysis must be done. Then the combustion efficiency of the coal must be calculated, the boiler efficiency is then determined by a boiler "acceptance test", or heat balance. The steam is then run through an engine driving a generator to determine the total plant efficiency thus determining how much coal is burned to produce a set amount of electricity. Several publications on Steam power plant operation explain these efficiency tests in more detail.
If 35 percent of the fuel is converted into electricity this is called the what of the power plant?
It is the efficiency of the power plant.
What is the efficiency of hydro power plant?
It is around 35 to 40 %
Which engine wastes the most energy?
I would say, heat engine on earth would waste the most energy since it is always limited by thermodynamic efficiency to have some loss. In general, lower the temperature difference will resulted to lower the efficiency, a simple steam engine for a train would be of lower efficiency than a internal combustion engine and lower than complex high pressure steam turbine and is probably the lowest engine efficiency in commercial scale.
What is STG power plant?
STG stands for steam turbine generator which is one component of a power plant
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
What is reheat factor in power plant?
The reheat factor in the steam turbine refers to the Thermodynamic effect on the turbine efficiency. Others factors includes the cumulative heat, and the steam turbine condition curve.
How superheating of steam improves the efficiency of thermal power plant?
The amount of energy transferred from the steam is a function of the temperature difference between the input and output of the turbine. Also, superheating the steam ensures that there are no water molecules that can damage the turbine blades.
How much coal does a 10 MW power plant use daily?
Coal releases about 14-15,000 btu's of heat per pound. This will on average produce about 12 lbs of high quality superheated steam. With a **steam rate of an engine at about 4 lbs of steam per kilowatt produced, this coal plant can produce about 3 kilowatts per pound of coal burned. So to produce 10 MW of electricity this hypothetical plant will burn about 3,334 lbs. of coal per hour. In a day the coal consumed will be about 80, 000 lbs or 40 tons. *Actual fuel conditions, combustion efficiency, boiler efficiency and engine efficiency would need to be determined for any particular power plant to determine actual coal usage in that plant. **steam rates of different power plants can range from about 3.5 lbs steam/ KW to more than 10 lbs of steam/ KW.
What is boiler combustion efficiency?
boiler efficiency is how much water is converting to steam.
Why is superheated steam at high pressure frequently employed in the steam cycle?
The efficiency of power plant based on the Rankine Cycle can be calculated from the Temperature-Entropy (Ts) Diagram. Area on the Ts Diagram represents energy. The efficiency of the cycle can be calculated by dividing WorkOut (the area enclosed by the cycle) by HeatAdded. Note that HeatAdded - WorkOut = HeatRejected. Increasing the steam temperature and pressure improves the ratio of these areas. Where the pressure is increased to above the Critical Point, the steam plant is described as Super Critical. Increasing the degrees of superheat in the steam also reduces the wetness of the steam in the last row of blades in the turbine.
A steam turbine has an efficiency of 40 percent A steam engine has an efficiency of 25.0 percent Suppose both devices are provided with 1000J of thermal energy How much more useful work will the ste?
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.
What is lp and hp heaters?
In regenerative cycle LP/HP heaters are used to raise condensate/feed water temperature by extracting/bleed steam from LP and Hp stages of steam turbine in order to improve the efficiency of the plant
