Magawo akulu, okonda fani, ali anayi mu kuchuluka: Kutha (V) Kupanikizika (p) Kuchita bwino (n) Kuthamanga kwazungulira (n min.-1)
Kutalika kwake ndi kuchuluka kwa madzimadzi omwe amasunthidwa ndi fanasi, voliyumu, mkati mwa kanthawi kochepa, ndipo nthawi zambiri amawonetsedwa mu m3/ h, mamita3/ Mph., m3/ gawo.
Mphamvu zonse (pt) ndi kuchuluka kwa kupsinjika kwapadera (pst), mwachitsanzo, mphamvu yofunikira yolimbana ndi mikangano yotsutsana ndi makinawa, ndi mphamvu yamphamvu (pd) kapena mphamvu yamphamvu yomwe imaperekedwa kumadzimadzi oyenda (pt = pst + pd ). Mphamvu yamphamvu imadalira kuthamanga kwamadzi (v) ndi mphamvu yokoka (y).
Kumene:
pd = kuthamanga kwakukulu (Pa)
y = mphamvu yokoka yamadzimadzi (Kg / m3)
v = kuthamanga kwamadzimadzi potsegulira zimakupiza zomwe zimagwiritsidwa ntchito ndi kachitidwe (m / sec)
Kumene:
V = mphamvu (m3 / sec)
A = n'zotsimikizira za kutsegula ntchito ndi dongosolo (m2)
v = kuthamanga kwamadzimadzi potsegulira zimakupiza zomwe zimagwiritsidwa ntchito ndi kachitidwe (m / sec)
Kuchita bwino kwake ndi chiŵerengero pakati pa mphamvu zoperekedwa ndi fanasi ndi kulowetsa mphamvu kwa zimakupiza zoyendetsa galimoto
Kumene:
n = kuchita bwino (%)
V = mphamvu (m3 / sec)
pt = mphamvu yamphamvu (KW)
P = kupanikizika kwathunthu (daPa)
Kuthamanga kwazungulilo ndi kuchuluka kwa zosintha zomwe zimayendetsa zimakupiza kuti ziziyenda bwino.
Pamene kuchuluka kwamasinthidwe kumasiyanasiyana (n), pomwe mphamvu yokoka yamadzi imakhazikika (?), Kusiyanaku kumachitika:
Mphamvu (V) ndiyofanana molingana ndi liwiro la kasinthasintha, chifukwa chake:
Kumene:
n = liwiro la kasinthasintha
V = mphamvu
V1 = mphamvu yatsopano yomwe imapezeka pakusinthasintha kwa liwiro
n1 = liwiro latsopano la kasinthasintha
Kumene:
n = liwiro la kasinthasintha
pt = kukakamizidwa kwathunthu
pt1 = kupanikizika kwatsopano komwe kumapezeka pakusintha kwachangu
n1 = liwiro latsopano la kasinthasintha
Mphamvu yolowetsa (P) imasiyanasiyana ndi kyubu yazungulira potembenuka, chifukwa chake:
Kumene:
n = liwiro la kasinthasintha
P = abs. mphamvu
P1 = kuyika kwamagetsi kwatsopano komwe kumapezeka pakusinthasintha kwa liwiro kwa kasinthasintha
n1 = liwiro latsopano la kasinthasintha
Mphamvu yokoka (y) ikhoza kuwerengedwa ndi njira yotsatirayi
Kumene:
273 = zero kwathunthu (° C)
t = nyengo yamadzimadzi (° C)
y = mphamvu yokoka ya mpweya pa t C (Kg / m3)
Pb = kuthamanga kwa barometric (mm Hg)
13.59 = mphamvu yokoka ya mercury ku 0 C (kg / dm3)
Pofuna kuwerengera, kulemera kwa mpweya pamatenthedwe osiyanasiyana komanso kutalika kwa asl kwaphatikizidwa patebulo pansipa:
