a DC load with a power factor above 1 — motors, transformers and other inductive loads — the real power that does useful work is P = V × I × PF, while the product V × I alone gives the larger apparent power in volt-amperes. This calculator reports the power in watts, kilowatts and mechanical horsepower, using 1 hp = 745.7 W. If instead it were a motor with a power factor of 0.8, the real power would fall to 120 × 10 × 0.8 = 1,200 W, which is about 1.2 hp or about 1.61 hp. Multiply by your price per kWh for the daily cost and by 30 for the monthly estimate. Daily energy in kilowatt-hoursThe advanced usage fields turn power into running cost.

Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani formula ya mphamvu yamagetsi?
Mphamvu yachikhalidwe yamagetsi ndi P = V × I × PF. Kwa DC kapena resistive kunyamula mphamvu factor ndi 1, kotero mphamvu ndi mwachindunji voltage nthawi yatsopano.
Kodi pali ma watts angati mu horsepower?
Mmodzi wa makina horsepower ndi 745.7 watts, choncho 1492 W kulemera ndi zokhudza 2 hp.
Kodi ndi chiyani chiopsezo choyendetsa?
Mphamvu ya tsiku ndi tsiku ndi mphamvu (kW) × maola tsiku lililonse, m'ma kWh.Kukulitsa ndi masiku 30 ndi mtengo wanu pa kWh kuti muwerenge mtengo wa mwezi.
Kodi ndi chiyani power factor ndi pamene ine kusintha izo?
Power factor ndi gawo la mphamvu yooneka (V × I) yomwe imachita ntchito yoyenera. Ndi 1 kwa DC ndi zonyamula zotsutsana monga ma heaters ndi ma bulbs owala, koma amagwa mpaka pafupifupi 0.7-0.9 kwa ma motors ndi zinthu zambiri zamagetsi, kuchepetsa ma watts anzeru.
Kodi pali kusiyana kotani pakati pa ma watts ndi volt-amperes?
Watts ndi mphamvu yachikhalidwe (V × I × PF); volt-amperes ndi mphamvu yooneka (V × I) popanda kusintha kwa mphamvu-factor. Kwa zonyamula zotsutsana ndi iwo ndi ofanana, koma kwa zonyamula zoyankhulana VA rating ndi pamwamba, chifukwa chake generator ndi UPS ratings ndi zoperekedwa mu VA.
Kodi ndingasinthe bwanji ma watts kuti ndigwiritse ntchito?
Kugawa Watts ndi 745.7.So 1,200 W ndi zokhudza 1.61 hp, ndi 1 hp motor amatenga pafupifupi 746 W ya makina-kugwirizana mphamvu (zambiri ndi magalimoto, pamene kuwonongeka kwa efficiencies ndi kuphatikizidwa).
