Everyday wind turbine profit problems come down to one relationship between air density, airflow area, turbine efficiency, price of electricity, time of generation, wind turbine cost and wind speed in your area. This calculator turns those numbers into total energy! (not power) of the wind (to be hidden), wind turbine generated power and kw of the turbine (to be hidden), with the working shown so you can check the result rather than simply trust it.
What Is the Wind Turbine Profit Calculator?
The wind turbine profit calculator works out total energy! (not power) of the wind (to be hidden), wind turbine generated power and kw of the turbine (to be hidden) from air density, airflow area, turbine efficiency, price of electricity, time of generation, wind turbine cost and wind speed in your area.
Biological relationships are usually approximations rather than exact laws, so the output is best treated as an estimate with a sensible range around it.
How the Wind Turbine Profit Calculation Works
The calculation applies the relationship as published, step by step, so each intermediate value can be checked against the underlying theory.
Keep the units consistent throughout. Mixing a percentage with a proportion is the single most common source of an answer that is out by a factor of a hundred.
Assumptions Worth Knowing
Any relationship used here assumes a constant rate, a representative sample, or a stable population. Real populations rarely meet those conditions for long, so treat the answer as a guide.
Where the inputs are field measurements, a single misread value can shift the result noticeably. Measure carefully and record what you used.
A Worked Example
Working through an example, with air density set to 10, airflow area set to 5, turbine efficiency set to 2, the calculator returns total energy! (not power) of the wind (to be hidden) of 2,000, and kw of the turbine (to be hidden) of 4,000, and time in days (to be hidden) of 0.00012. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out total energy! (not power) of the wind (to be hidden)?
Enter air density, airflow area, turbine efficiency, price of electricity, time of generation, wind turbine cost and wind speed in your area. The calculator then works through the relationship and reports total energy! (not power) of the wind (to be hidden), wind turbine generated power and kw of the turbine (to be hidden).
What does the wind turbine profit actually calculate?
It takes air density, airflow area, turbine efficiency, price of electricity, time of generation, wind turbine cost and wind speed in your area and converts them into total energy! (not power) of the wind (to be hidden), wind turbine generated power and kw of the turbine (to be hidden) using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter air density?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
