Liis dhammaystiran oo ah qaacidooyinka xisaabinta qaboojiyaha ee caadiga ah!
Liis dhammaystiran oo ah qaacidooyinka xisaabinta qaboojiyaha ee caadiga ah!
1. Beddelidda heerkulka
Ka bilow beddelidda heerkulka koowaad ee ugu fudud
Celsius (C) iyo Fahrenheit (F)
Fahrenheit = 32 + Celsius × 1.8
Celsius = (Fahrenheit -32)/1.8
Kelvin (K) iyo Celsius (C)
Heerkulka Kelvin (K) = darajooyinka Celsius (C) +273.15
02, beddelidda cadaadiska
Mpa, Kpa, pa, bar
1Mpa = 1000Kpa;
1Kpa = 1000pa;
1Mpa = 10bar;
1bar = 0.1Mpa = 100Kpa;
1 cadaadiska jawiga = 101.325Kpa = 1bar = 1kg;
bar, Kpa, PSI
1bar = 14.5psi;
1psi = 6.895Kpa;
mH2O
1 kg/cm2 = 105 = 10 mH2O = 1 bar = 0.1 MPa
1 Pa = 0.1 mmH2O = 0.0001 mH2O
1 mH2O=104 Pa=10 kPa
03. Beddelidda xawaaraha dabaysha iyo mugga
1 CFM (cubic feet per minute)=1.699 M³/H=0.4719 l/s
1 M³/H=0.5886CFM (cubic feet/minute)
1 l/s=2.119CFM (cubic feet per minute)
1 fpm (cagaha daqiiqaddii) = 0.3048 m/min = 0.00508 m/s
04. Awoodda qaboojinta iyo awoodda
1 KW = 1000 W
1 KW = 861Kcal/h (kcal) = 0.39 P (Awoodda qaboojinta)
1 W = 1 J/s (Kaftan/sek)
1 USTR (tan qabow US) = 3024Kcal/h = 3517W (Awoodda qaboojinta)
1 BTU (Qaybta kuleylka Ingiriiska) = 0.252kcal/h = 1055J
1 BTU/H (Cutubka kuleylka Ingiriiska/saacad) = 0.252kcal/h
1 BTU/H (Unit thermal unit/hour) = 0.2931W (Awoodda qaboojinta)
1 MTU/H (kun unug kuleyl/saacad) = 0.2931KW (awoodda qaboojinta)
1 HP (koronto) = 0.75KW (koronto)
1 KW (koronto) = 1.34HP (koronto)
1 RT (awoodda qabow) = 3.517KW (awoodda qabow)
1 KW (awoodda qaboojinta) = 3.412MBH (103 cutubyada kuleylka/saacadda Ingiriiska)
1 P (awoodda qaboojinta) = 2200kcal/h = 2.56KW
1 kcal/h = 1.163W
05, qaaciddada xisaabinta fudud
1. Xulashada waalka fidinta: ton qabow + 1.25% margin
2. Awood saxaafadeed: 1P = 0.735KW
3. Kharashka qaboojiyaha: awoodda qaboojinta (KW) ÷ 3.516 × 0.58
4. Socodka biyaha ee mashiinka hawada qaboojiya: awoodda qaboojinta (KW) difference farqiga heerkulka ÷ 1.163
5. Socodka biyaha qabow ee mashiinka maroojiyaha biyaha qaboojiyey: awoodda qaboojinta (KW) difference 0.86 difference farqiga heerkulka
6. Qaboojinta socodka biyaha ee mashiinka fur-biyood-qaboojiyey: (awoodda qaboojinta KW + awoodda kombaresarada) difference 0.86 difference Farqiga heerkulka
06. Dhumucda khadka iyo awoodda qaboojinta
Mm 1.5mm2 waa 12A-20A (2650 ~ 4500W)
Mm 2.5mm2 waa 20-25A (4500 ~ 5500W)
★ 4 mm2 is 25-32A (5500~7500W)
★ 6 mm2 is 32-40A (7500~8500W)
