The following chart contains the maximum recommended flow rates at the given pressure for ANSI schedule 40 pipe. This chart is applicable for designing compressed air systems. The flow values in this chart are based on a pressure drop as set forth in the following schedule

Pressure Drop per 100 Feet of Pipe 10% of Applied Pressure 5% of Applied Pressure

Pipe Size - Inches 1/8, 1/4, 3/8, 1/2 3/4, 1, 1-1/4, 1-1/2, 2, 1-1/2, 3
