Таблица рассчитана при температуре воды 10° С.
Потери напора в изгибах, шаровых вентилях, тройниках и обратных клапанах соответствуют длине прямого трубопровода.
В следующей таблице в верхней части ячейки обозначены скорости протекания потока в м/с, а в нижней — потери напора в метрах на 100 м прямого трубопровода.
