Ukubalwa kwamandla kwesithando sokushisa sokungeniswa

Ungawabala kanjani amandla adingekayo ku isithando sokushisa sangaphakathi ukushisa ububanzi obungama-40 nobude bamamitha ayi-6? Ungabala kanjani ijubane?

Ukubalwa: Shisisa ikhilogremu yensimbi kusuka kuma-degree angama-25 kuye kwayi-1250 ngemizuzwana engama-60. Ukuthatha ukusebenza kahle kwe-heater ngu-0.5, amandla adingekayo ngu: 0.168 × ＜1250-25＞ × 1 ÷ 0.24 ÷ 0.5 ÷ 60 = 23.8kW.
