Hydraulic mean diameter provides a method by which non-circular pipe work and ducting may be treated as circular for the purpose of pressure drop and fluid flow rate calculations. This article provides the equations required to determine the hydraulic diameter for a range of non-circular geometries.

In other words it is the sum divided by the count. If the minimum wall thickness based on ASME standards is greater than the calculated minimum wall thickness, you may be legally required to use the minimum wall thickness given in the ASME standard. 172 (Formula App 17-5 (2)). Pipe Volume CalculatorVolume of water in pipe - calculation example. Let's see how to use the pipe volume calculator correctly. For an example calculation, we need a few assumptions. We will calculate the volume of a 6-meter length pipe, with an inner diameter equal to 15 centimeters. The pipe is used to transport water.

R = Hydraulic radius Sf = Friction slope When rearranged into a more useful form, in which in which:K = 1.486 AR2/3 n The Manning Equation for Partially Full Pipe Flow 5. Hydraulic Radius Less than Half Full Flow The hydraulic radius is one of the parameters needed for Manning equation calculations. Equations are available to calculate the hydraulic radius for known pipe diameter and depth of flow. The equations are slightly different depending on Useful Calculations - Mittler Bros Machine & ToolCLR(center line radius) x DOB (degree of bend) x .01745 Circumference of a circle = 3.14 x Diameter Weight of steel tubing in lbs per foot = 10.6802 x wall thickness x (diameter - wall thickness) Multiply inches x 25.4 to get millimeters Multiply millimeters x .03937 to get inches
