2.22: "Hurricane Fluttershy", Spoilers*Spoilers*SELF-CONSCIOUS FLUTTERSHY*Spoilers*Spoilers Options

[Guardian Prime]

The second Fluttershy episode of the season is almost here.

Hurricane Fluttershy: Fluttershy needs to overcome her self-consciousness in order to help Rainbow Dash and the other pegasi with the Rainy Season.

Looks like we'll get a few more new ponies in this one.

If all other factors are held to be constant (which, for most pegasi other than colts like Rumble or whateverthehells like Chunk Flanksteak), then you can use a speed measurement as a power measurement. Your dial just includes all those constants in the calibration.

Spitfire's giant anemometer was calibrated specifically for this sort of tornado, and presumably was designed to be placed far enough back that it wouldn't create turbulence and mess up the results, while up-multiplying the numbers appropriately. It may also be magicked to be frictionless and very low inertia.

The anemometer is arranged to measure perpendicular to the freestream, though, and isn't equal to the velocity of the freestream (=airspeed) even if it were parallel to the flow. Remember that relative to the pegasus the anemometer is moving at the freestream velocity itself, so its vanes are only capable of detecting the local accelerations of the flow relative to the freestream. With all the flapping wings and such, you aren't going to get from there to any sort of useful measurement in that environment. In a wind tunnel, you might have more luck, since you can keep the anemometer still relative to the pegasus, and with enough (magic) anemometers* and some math you might get somewhere. But it's a complicated experimental setup, I think.

So let's just give up on making any sense out of that, shall we? I think no good can come of it.

*Sufficiently magic anemometers actually exist. If you have enough control over the environment and don't mind some small particles in the flow, you can do laser Doppler velocimetry. Alternatively, hot wire anemometers or sonic anemometers are more flexible, though you don't get as much data as LDV can get you.
