Фактически нужно составить уравнение теплового баланса. Тепло поступившее в избу за час Q₁, должно равняться количеству теплоты ушедшему в окружающую среду Q₂. Поступающее количество теплоты {1} Где m -- интересующая нас, масса дров [кг]; q -- удельная теплота сгорания дров [Дж/кг]; η -- кпд печи 0,6
Теплота ,ушедшая в окружающий воздух за время t. {2} Где S -- площадь через которую уходит тепло [м²] σ -- Удельные теплопотери (количество тепла, ушедшее через единицу площади при единичной разности температур за 1с) T₂ -- Температура в избе T₁ -- Температура окружающей среды t -- Время в секундах 1ч = 3600 с. Итого, приравниваем выражения Q₁ и Q₂ из {1} и {2} .
Выражаем m {3} И подставляем в {3} числовые значения величин кг
