Pipe Sizing and Flow Calculation Software
AioFlo uses a single form to allow selection of Sch 10S, 40 or 80 pipe in a range of sizes from 1/2 inch to 24 inch NB.
In the fields where AioFlo requires you to specify the inside diameter of the pipe you can enter it as a number, or you can click the ellipsis button to bring up this form and simply select it. Note that the form lists the NB sizes in inches and millimeters, and also gives the actual inside diameter in the units specified in the top right corner.
From this pop-up page you can select from a wide range of materials, finishes and conditions for the pipe roughness.
In non-laminar flow the friction factor, and therefore the pressure drop, is dependent on the pipe roughness. Using the correct roughness for the type of pipe in use is important in being able to accurately predict the pressure drops and flows. AioFlo allows you to enter your own pipe roughness value in the Main Screen, or you can click the ellipsis button to bring up this window and select the applicable material and condition to give the correct roughness for your pipe.
