Elektr isitish trubasining sirt yukini qanday hisoblash mumkin? Elektr isitish trubasining sirt yuki isitish trubasining isitish yuzasida birlik maydoniga to'g'ri keladigan quvvatdir.
Elektr isitish trubkasi sirt yukini hisoblash formulasi:
Elektr isitish trubkasi sirt yuki (w/sm2 (vatt zichligi))=Vt (elektr isitish trubkasi quvvati)/D × p × L (sm)
Ular orasida D=isitish trubasining diametri; (p=3,1416); (L=isitish qismining uzunligi);
Shuni ta'kidlash kerakki, L - elektr isitish trubasining umumiy uzunligi emas, balki isitish uzunligi, chunki har bir isitish trubkasi isitish uzunligi va sovuq zonaga ega bo'ladi.

Elektr isitish trubasining oqimini qanday hisoblash mumkin:
Isitish trubkasi yoki paketida ko'rsatilgan quvvat va kuchlanishga qarang, oqim=quvvat / kuchlanish
Elektr isitish trubkasi quvvatini hisoblash:
1. Empirik hisoblash-P=haqiqiy oqim / 1,5=78/1,5=52 kilovatt; 2. Formulani hisoblash-P=IU, P=√3UxIx, bu erda Ux - tarmoq kuchlanishi, Ix - chiziq oqimi, P=√3UxIx= √3×380×78≈52 kilovatt. 11 Elektr quvvati P tokning qarshilikka tushgan kvadratiga teng P=IIR (Umumiy formula) Elektr quvvati P=UI=380V×78A=29640W4 kuchlanishga koʻpaytirilgan oqimga teng.
