Yuksiz qushning havo tezligi soatiga taxminan 20,1 mil. Bu qushning havo tezligini aniqlash uchun Strouhalni hisoblash orqali aniqlanadi. Strouhal soni St = fstD / U sifatida belgilanadi, bu erda fst - bu tanalarning to'xtashdagi vortex tezligi (yoki Strouhal chastotasi), D - aylanma silindrning diametri va U - atrof-muhit oqimining tezligi.
