Mphamvu ya mphepo poyezera kulondola

Zotsatira za mphepo ndizofunikira kwambiri posankha zolondolakatundu cell sensor mphamvundikusankha kukhazikitsa koyenera kuti mugwiritse ntchitontchito zakunja. Powunika, ziyenera kuganiziridwa kuti mphepo imatha (ndipo imachita) kuwomba kuchokera kumbali iliyonse yopingasa.

Chithunzichi chikuwonetsa mphamvu ya mphepo pa thanki yoyima. Zindikirani kuti sikuti pali kugawanika kokakamiza kumbali ya mphepo, koma palinso kugawa "kukoka" kumbali ya leeward.

Mphamvu za mbali zonse za thanki ndizofanana mu kukula koma mosiyana ndi momwe zimayendera ndipo motero sizimakhudza kukhazikika kwa sitimayo.

Liwiro la Mphepo

Kuthamanga kwakukulu kwa mphepo kumadalira malo, mtunda ndi malo omwe amakhalapo (zomangamanga, malo otseguka, nyanja, etc.). Bungwe la National Meteorological Institute litha kupereka ziwerengero zambiri kuti zitsimikizire momwe mphepo iyenera kuganiziridwa.

Werengani mphamvu yamphepo

Kuyikako kumakhudzidwa makamaka ndi mphamvu zopingasa, zomwe zikuyenda molunjika mphepo. Mphamvu izi zitha kuwerengedwa ndi:
F = 0.63 * cd * A * v2

ili pano:

cd = kukokera kokwanira, kwa silinda yowongoka, kukoka kokwana ndikofanana ndi 0.8
A = gawo lowonekera, lofanana ndi kutalika kwa chidebe * chotengera chamkati chamkati (m2)
h = kutalika kwa chidebe (m)
d =Bowo la sitima (m)
v = liwiro la mphepo (m/s)
F = Mphamvu yopangidwa ndi mphepo (N)
Chifukwa chake, pa chidebe chowongoka chowoneka bwino, njira iyi ingagwiritsidwe ntchito:
F = 0.5 * A * v2 = 0.5 * h * d * v2

Pomaliza

•Kuyika kuyenera kupewa kugubuduzika.
• Zinthu zamphepo ziyenera kuganiziridwa posankha mphamvu ya dynamometer.
•Popeza mphepo simawomba mopingasa nthawi zonse, choyimiriracho chingayambitse vuto la kuyeza chifukwa cha kusintha kwa ziro. Zolakwa zazikulu kuposa 1% ya kulemera kwa ukonde zimatheka pa mphepo yamphamvu kwambiri> 7 Beaufort.

Zotsatira pa Kayendetsedwe ka Ma Cell ndi Kuyika

Zotsatira za mphepo pa zinthu zoyezera mphamvu ndizosiyana ndi momwe zimakhudzira zombo. Mphamvu ya mphepo imayambitsa mphindi yogubuduza, yomwe idzathetsedwa ndi nthawi yomwe cell yolemetsa imachita.

Fl = mphamvu pa sensor yokakamiza
Fw = mphamvu chifukwa cha mphepo
a = mtunda pakati pa maselo onyamula katundu
F*b = Fw*a
Fw = (F * b)∕a
