Jul 07, 2016Friction loss is a pressure loss caused by water flowing through pipes, fittings and component parts. The interior surfaces create friction on the moving water, which reduces the water pressure. This happens in the water meter, pipes, fittings, valves and backflow prevention devices. 5-4-2-3-1 ways to measure normal pressure loss Friction loss irrigation pipe friction loss in turkmenistan
