Как рассчитать диаметр трубопровода по расходу

В процессе проектирования систем центрального отопления крайне необходимо рассчитывать внутренний диаметр подводящих, отводящих и магистральных трубопроводов.

Скорость движения теплоносителя для общественных и жилых зданий в пределах 1,5 м/с, и не менее 1,3 м/с для предотвращения образования воздушных пробок.
