Таблица рассчитана
по новой формуле Г. Ланга с величиной а = 0,02 при температуре воды 10° С.
Потеря напора в
коленах, запорных задвижках, тройниках и обратных клапанах соответствует длине
прямого трубопровода, как указано в обеих последних строчках таблицы. Потеря
напора в приемных клапанах соответствует двойной потере в тройнике.
Потери напора в трубопроводах
из полимерных материалов
В таблице выделенным
шрифтом обозначены скорости протекания потока в м/с, а обычным — потери напора
в метрах на 100 м прямого трубопровода.
