what is the wind speed velocity of an unburdened sparrow?

actually that was..\n\n"What is the air speed velocity of an unladen swallow?"\n\n"African or European?"\n\n"I don't know that....ahhhhhhhhh!"\n\n"Well you have to know these things when you're king."

For small hummers like Ruby-throated, about 55 times per second. Normal flight speed is about 25 MPH.

It really does depend.  Maybe 20 to 50 miles +/-  Sometimes they will pass by in a few minutes, other times 1/2 hour.  Don't run around outside just because the wind stops blowing.

What do you mean, an African or European Swallow?\nIn order to maintain air speed velocity a swallow needs to beat its wings 43 times every second, right?\n\nActually, the correct answer appears to be the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles an hour.

I did a google and there are different models, so I'm not sure which one you need info about. But, the photo of the model at the site below looks pretty simple--as if you merely hold it in the path of the airflow, and read the speed of the wind. It says the model is intended for students.

Sparrow hawk is not that large. Most probably a norther harrier male. They average about 20 in. in length. The key field mark is a white rump. It is very evident in flight. The males are gray above and lighter gray below. There is a possibility that it was a northern goshawk but they are uncommon. They have a broad white eyebrow that is very evident. They are not white below but a dull light gray.

First find Vo:  Vo^2 = Rg/sin(28)  Where R = range & 8 = theta\n\nUsing your numbers, Vo = 41.523 m/s\n\nImpulse = change in momentum ----> Ft = mVo---> F = mVo/t\n\nSo, F = (.0431kg*41.523m/s)/.00438sec = 408.59 N\n\nVoila!

Duh!\n\nAfrican or European?\nThe air speed velocity of an unladen African Swallow= 38 to 40 mph revised Strouhal numbers based on that study all lead me to estimate that the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles an hour.

I'm keeping the sparrows captive in my living room, and there's nothing anybody can do about it!\n\nor not\n\n-quoted from wikipedia-\n\nThe Old World true sparrows are found indigenously in Europe, Africa and Asia. In Australia and the Americas, early settlers imported some species which quickly naturalised, particularly in urban and degraded areas. House Sparrows, for example, are now found throughout North America, in every state of Australia except Western Australia, and over much of heavily populated parts of South America.\n\n-end quote-\n\nor not

Left or right? <g>\n\n15 to 80 times per second (depending on the size of the bird).\n\nMultiply that by 60, OK?\n\n"Q: How fast do hummingbirds flap their wings? \n A: For small hummers like Ruby-throated, about 55 times per second. Normal flight speed is about 25 MPH." \n\nSee link ...

You'll actually make the measurement worse. Think about the math without going in to numbers too much. Let's say we have 30 arms (yeah, I know, too many). Only one of them at a time is nearly perpendicular to the wind force. It's plus/minus 6 degrees. By the time that one move past that 6 degrees the next is coming in. Think about the sines and cosines - the force parallel and perpendicular - nearly 100% is going in the direction of the wind. It moves that blade just about right.\n\nNow go from 30 to 3 blades.Each blade now covers 120 degrees. That makes them the most perpendicular plus/minus 60 degrees. Now look at the sines and cosines of the forces. You actually get quite a bit of force slowing down your reading. If you hooked up your anemometer to an o'scope, you would see a pretty drastic fluctuation in speed variance. The more arms, the flatter that variance becomes.

Yes, sound travels faster downwind than upwind or with no wind. The speed of sound is constant relative to the medium it is traveling through. So if that speed is 1000 ft/sec, then in the downwind direction the speed is 1000 ft/sec + the wind speed. However the helpful effect this would have on calling to someone downwind from you might be canceled out by the extra noise the wind produces.

would depend on the mass, and air resistance of the arrow. as arrows have most of their weight at one end I guess they will fall very weell, and with quite low air resistance. a guess would be well in excess of 200 mph, a diving bird of prey can get close to this and an arrow wil have a much smaller profile, but as speed increses the gai you get will diminish. you could try putting numbers in a simulator online if you have some.(like this one below)
