yana nan:
cd = ja coefficient, don silinda madaidaiciya, madaidaicin ja yana daidai da 0.8
A = sashin da aka fallasa, daidai da tsayin akwati * diamita na ciki (m2)
h = tsayin akwati (m)

F = Ƙarfin da iska ta haifar (N)
Don haka, don kwantena cylindrical madaidaiciya, ana iya amfani da dabara mai zuwa:
F = 0.5 * A * v2 = 0.5 * h * d * v2
