Migumisiro yemhepo yakakosha zvikuru pakusarudza yakaruramaload cell sensor capacityuye nekuona iyo chaiyo yekumisikidza yekushandisa mukatizvekunze zvikumbiro. Mukuongorora, zvinofanirwa kufungidzirwa kuti mhepo inogona (uye inoita) kuvhuvhuta kubva kune chero nzira yakachinjika.
Dhiagiramu iyi inoratidza kuita kwemhepo patangi rakamira. Cherechedza kuti kwete chete kune kugoverwa kwekumanikidzika kudivi remhepo, asi kunewo "kusveta" kugovera padivi reeward.
Masimba ari kumativi ose etangi akaenzana muhukuru asi akapesana negwaro uye naizvozvo haana simba pakugadzikana kwese kwechikepe.
Mhepo Speed
Iyo yakanyanya kumhanyisa mhepo inoenderana nenzvimbo yenzvimbo, urefu uye mamiriro enzvimbo (zvivakwa, nzvimbo dzakavhurika, gungwa, nezvimwewo). National Meteorological Institute inogona kupa mamwe manhamba ekuona kuti kumhanya kwemhepo kunofanirwa kutariswa sei.
Verenga simba remhepo
Kuiswa kunonyanya kukanganiswa nemasimba akadzikama, achiita nenzira yemhepo. Aya masimba anogona kuverengerwa ne:
F = 0.63 * cd * A * v2
iri pano:
cd = dhonza coefficient, kune silinda yakatwasuka, iyo yekudhonza coefficient yakaenzana ne0.8
A = chikamu chakafumurwa, chakaenzana nekukwirira kwemudziyo * mudziyo wemukati dhayamita (m2)
h = kureba kwemudziyo (m)
d =Gomba rengarava(m)
v = kumhanya kwemhepo (m/s)
F = Simba rinogadzirwa nemhepo (N)
Naizvozvo, kune yakatwasuka cylindrical mudziyo, inotevera fomula inogona kushandiswa:
F = 0.5 * A * v2 = 0.5 * h * d * v2
Mukupedzisa
•Kuiswa kunofanira kudzivirira kupidigura.
• Mhepo zvinhu zvinofanirwa kutariswa pakusarudza dynamometer kugona.
•Sezvo mhepo isingawanzovhuvhuta yakananga kwakachinjika, chikamu chakati chechetere chinogona kukonzera kukanganisa pakuyera nekuda kwekuchinja kusina kujeka kwe zero point. Zvikanganiso zvakakura kudarika 1% yehuremu hwemambure zvinogoneka chete mumhepo ine simba>7 Beaufort.
Mhedzisiro paKutakura Sero Kushanda uye Kuiswa
Mhedzisiro yemhepo pazvinhu zvekuyeresa simba zvakasiyana nezvinoita pangarava. Simba remhepo rinokonzera nguva yekupidigura, iyo inozogadziriswa nekuita nguva yekutakura sero.
Fl = simba pakumanikidza sensor
Fw = simba nekuda kwemhepo
a = chinhambwe pakati pekutakura maseru
F*b = Fw*a
Fw = (F * b)∕a
