Compare a wind-gauge reading with an independently known reference speed. A selected exponent shows how a hypothetical power ratio would respond to that speed difference; it does not measure turbine output.
Wind Gauge Interactive Calculator
Enter gauge reading, independently known reference wind and a chosen exponent. Power shown and loss are hypothetical ratio transforms—not measured energy or a calibration certificate.
Equation Used
- Reading and reference are simultaneous scalar wind speeds.
- Reference speed is entered independently and treated as known.
- Exponent is a user-selected sensitivity model.
- No air density, area or power coefficient is used.
- Direction, turbulence, dynamic response and calibration uncertainty are omitted.
Wind-Reading Sensitivity Screen
The U.S. Department of Energy explains wind-energy context. This tool generalizes the exponent and does not calculate turbine power.
What This Calculator Represents
A reading/reference comparison and user-selected exponent transform.
Ratio Sensitivity
S=100r
Pshown=100r^n
Ploss=100(1-r^n)
Worked Scenario
At 6.0 m/s reading, 6.4 m/s reference and n=3, speed ratio is 93.8%, hypothetical power shown about 82.4%, loss 17.6%, and wind miss 0.4 m/s.
Assumptions and Limits
No instrument calibration, uncertainty, wind direction, turbulence or actual turbine power is calculated.
Frequently Asked Questions
Is true wind measured by this tool?
No; it is entered.
Why can loss be negative?
The reading may exceed the reference.
Is exponent always three?
No; it is entered.
Is power in watts?
No; it is a ratio only.
Is calibration uncertainty included?
No.
Can this certify a gauge?
No.
