Beddeliyaha awoodda

Dulmar ku saabsan unugyada awoodda

Awooddu waxay cabbirtaa sida degdegga ah ee tamar loo beddelo ama loo gudbiyo. Meelo kala duwan ayaa adeegsada unugyo kala duwan: korontada waxaa la adeegsadaa watt iyo volt‑ampere, HVAC‑ga BTU iyo tan qaboojin, makaanikadana xoogga faraska. Halkan waxaa ku yaal dulmar kooban oo ku saabsan unugyada beddelaha iyo sida ay ula xiriiraan watt.

Aasaaska SI

• Watt (W), kilowatt (kW), megawatt (MW), gigawatt (GW), terawatt (TW), petawatt (PW) - Heerka SI; 1 kW = 1,000 W, 1 MW = 1,000,000 W, iwm. Waxaa loo adeegsadaa awoodda koronto iyo makaanik.

Qoyska horsepower

• Horsepower (hp) - Makaanik/imperial ≈ 745.7 W, caadi u ah matoorada.
• Horsepower metric (PS) - ≈ 735.5 W, caan ah Yurub/baabuur.
• Horsepower koronto (hp(E)) - ≈ 746 W, qeexid rasmi ah.
• Horsepower boiler (hp(S)/bhp) - ≈ 9,809.5 W, loogu talagalay foornooyinka uumiga.
• Horsepower hydraulic - Ku dhow hp makaanikada, nidaamyada hawo/ dareere.
• Horsepower qaboojin - ≈ 3,517 W (qiyaastii hal tan qaboojin halkii hp).

Kulayl iyo HVAC

• BTU saacad/daqiiqad/ilbiriqsi - 1 BTU/h ≈ 0.293 W; caan ku ah kululaynta/qaboojinta.
• Therm saacad/daqiiqad/ilbiriqsi - 1 therm = 100,000 BTU; lagu arko biilasha gaaska.
• Caloriyada iyo kilocaloriyada s/min/h - 1 cal ≈ 4.184 J; unugyo kululaynta duug ah.
• Mcal/Gcal s/min/h - Unugyo waaweyn oo kulayl ah warshado.
• Tan qaboojin (TR) - 1 TR ≈ 3,516.85 W; lagu qiimeeyo awoodda qaboojinta.

Heerarka shaqada makaanikada

• Foot‑pound s/min/h (ft·lb/s) - 1 ft·lb/s ≈ 1.3558 W.
• Kilogram‑meter s/min (kg·m/s) - 1 kg·m/s ≈ 9.80665 W.

Awoodda koronto iyo falcelin

• Volt‑ampere (VA, kVA, MVA) - Awood muuqata oo AC ah.
• Volt‑ampere reactive (var, kvar, Mvar) - Awood falcelis la xiriirta danab/koronto falcelis.
• dBm, dBW - Heerar log ah oo ku xiran 1 mW ama 1 W, caadi ah RF/telecom.
• C·V/s, A·Ω/s - U dhigma watt; qaabab nadiif ah oo P = V·I ama P = I²·R.

CGS iyo sayniska

• Erg s/min/h - 1 erg = 1e‑7 J; ku jira qoraallo saynis oo duug ah.
• Dyn·cm/s, dyn·m/s - Qaabab CGS; 1 dyn·cm/s = 1e‑7 W.

Cilmiga xiddigaha iyo xad-dhaafka

• Iftiinka qorraxda (L☉) - ≈ 3.828e26 W; faa’iido leh marka la barbar dhigo awoodda xiddigaha.
• Iftiinka bolometric - Wadarta awoodda shucaaca dhammaan hirarka, badanaa lagu muujiyo L☉.
• Iftiinka neutrino - Mararka qaar loogu isticmaalo dhacdooyinka astrophysical, lagu beddeli karo watt.
• Planck power - ≈ 3.63e52 W, cabbir fikradeed oo ka imanaya joogtooyinka aasaasiga ah.

Talooyin wax ku ool ah

• U dhig unugga duruufaha: VA/var/kVA/MVA marka la naqshadaynayo AC; hp ama kW matoorada; BTU/h, TR, kcal/h ama therms kuleylinta/qaboojinta.
• Awood muuqata vs mid dhab ah: kW waa awood dhab ah, kVA muuqata, kvar falcelis. Qodobka awoodda (kW/kVA) waa muhiim oo go’aamiya cabbirka qalabka iyo khidmadaha.
• Kala duwanaanshaha hp: hp imperial (~745.7 W) iyo metric (~735.5 W) waxay kala duwan yihiin ~1-2%. Horsepower boiler aad buu uga weyn yahay - ha isku darin kuwa makaanikada.
• Kuleyl vs koronto: 1 tan qaboojin (~3.5 kW qaboojin) macnaheedu maaha 3.5 kW koronto; isticmaalka dhabta ah wuxuu ku xiran yahay EER/COP.
• RF ee dB: +10 dB = 10× awood, +3 dB ≈ 2×. 30 dBm = 1 W; 0 dBW = 1 W.
• Saldhigga waqtiga: BTU/h vs BTU/min vs BTU/s iyo cal/min vs cal/h farqi 60 ama 3,600; mar walba barbar dhig isla saldhigga waqtiga.
• Kuleylinta vs qaboojinta: TR, BTU/h, kcal/h waa caadi HVAC; therms iyo kW waxaa laga helaa gaaska/kuleylka korantada. U beddel kW kahor intaadan isbarbar dhigin qiimaha ama waxtarka.
