Imiphumela yomoya ibaluleke kakhulu ekukhetheni okulungileumthamo we-cell sensornokunquma ukufakwa okulungile ukuze kusetshenziswe ngaphakathiIzicelo zangaphandle. Ekuhlaziyeni, kufanele kucatshangwe ukuthi umoya ungavuza (futhi wenze) kunoma yisiphi isiqondisi esivundlile.
Lo mdwebo ukhombisa umphumela womoya ethangi elithe mpo. Qaphela ukuthi akukhona nje kuphela lapho kusatshalaliswa kwengcindezi ohlangothini lwamanzi, kepha kukhona futhi nokusatshalaliswa "kokumunca" ohlangothini lwe-leeward.
Amabutho ezinhlangothini zombili zethangi alingana ngobukhulu kepha ngokungafani ngakho-ke akunamthelela ekuqineni okuphelele komkhumbi.
Isivinini somoya
Isivinini somoya esiphezulu sincike endaweni yendawo, ukuphakama kanye nezimo zasendaweni (izakhiwo, izindawo ezivulekile, ulwandle, njll.). Isikhungo seNational Meteorological singanikeza ngezibalo eziningi ukunquma ukuthi ijubane lomoya kufanele libhekwe kanjani.
Bala amandla omoya
Ukufakwa kuthinteka kakhulu amabutho avundlile, enza ngokuqondisa komoya. Lawa mandla angabalwa ngu:
F = 0.63 * CD * A * V2
Kulapha:
CD = Hudula Coefficient, kwisilinda eqondile, i-coeffic yehudula ilingana no-0.8
Isigaba = esiveziwe, esilingana nokuphakama kwesiqukathi * Isitsha sangaphakathi (M2)
H = Ukuphakama kwesiqukathi (m)
d = umgodi womkhumbi (m)
v = isivinini somoya (m / s)
F = Force okukhiqizwe ngumoya (n)
Ngakho-ke, ngesitsha esiqondile se-cylindrical, ifomula elilandelayo lingasetshenziswa:
F = 0.5 * A * V2 = 0.5 * h * d * v2
Ekuphetheni
• Ukufakwa kufanele kuvimbele ukuchitha.
• Izici zomoya kufanele zibhekwe lapho ukhetha umthamo we-dynamometer.
• Njengoba umoya awuhlali ushaya endaweni evundlile, isakhi esithe mpo singadala amaphutha okulinganisa ngenxa yokushintshwa kwamaphoyinti we-zero wokuphikisana. Amaphutha amakhulu kune-1% yesisindo se-net kungenzeka kuphela emimoyeni enamandla kakhulu> 7 Beaufort.
Imiphumela ekusebenzeni kweseli lomthwalo nokufakwa
Umphumela womoya on force ukulinganisa izinto uhlukile kumthelela emikhunjini. Amandla omoya adala umzuzu wokubhidlizwa, okuzosuswa ngumzuzu wokuphendula weseli lomthwalo.
Fl = Force on inzwa yokucindezela
Fw = amandla ngenxa yomoya
A = Ibanga phakathi kwamaseli omthwalo
F * b = fw * a
Fw = (f * b) / a
