Water Pipe Flow Rate Table For Pipes Up To 2 Inches In Diameter - This water flow rate table shows water flow through pipes and copper tubing. Volume of flow is at one foot per minute velocity in Pipe or Tube. Schedule 40 pipe Dia. inches Cubic ft/min Gallons/minute 1/8
From the graph, this means the water speed will be 2 metres per second and the head required to achieve this flow rate will be 4,000 N/sq.m. (or 1.3 feet height of water) per metre of pipe. So if the sink is fed from a pipes 13 feet above it, the pipe run could have an (equivalent) length of 10 metres.
