Elliptical pipe has a slighlly greater capacity than round pipe. The term "round equivalent" is a misnomer, and elliptical and arch pipe should not be considered equal alternates. The designer may refer to the "concrete pipe de sign manual" for flow coefficient values.
The equivalent diameter is the diameter of a circular duct or pipe that for equal flow gives the same pressure loss or resistance as an equivalent rectangular duct or pipe. A round shape results in lower pressure drops and less fan horsepower to move the air and, consequently, smaller equipment.Elliptical pipe to round pipeProcessing HC Duct Calc Hart & CooleyEquivalent Duct Calculator.

How to Convert a Round Duct to Rectangular HunkerJul 17, 2017· Multiply this number by 3.14 (pi) to get the area of the round duct in square inches for example, 16 x 3.14 = 50.24 square inches.
DN or Diameter Nominal is International designation (SI or Matric Designator) and also a European equivalent of NPS to show pipe sizes. Here, you have to note that DN shows pipe sizes differently than NPS. 2 pipe is simply mentioned as DN 50. You can get any NPS to DN by multiplying it with 25.

2.1 Equivalent Diameter of PipesLiquid Pipelines. Because each of the parallel pipes in Figure 11.3 has a common pressure drop, we can replace all the parallel pipes between B and E with one single pipe of length L E and diameter D E so that the pressure drop through the single pipe at flow Q equals that of the individual pipes as follows:HC Duct Calc Hart & CooleyEquivalent Duct Calculator.

Check the below table for easy understanding.Pressure Loss from Fittings Equivalent Length Method Fittings such as elbows, tees and valves represent a significant component of the pressure loss in most pipe systems. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method. The strength of the equivalent length method is that it is very simple to calculate. The weakness of the equivalent length method is that

The area will cover a two dimensional slice of the duct. To then convert that to volume, you multiply the resulting area by the length. These calculations can be useful if you are figuring out flow numbers, trying to gauge material amounts or performing any
pipe cross section, and miter elbows. Values for pressure loss through system components are eed as equivalent feet of round, straight pipe, in Table I. Pressure losses also result from flow measurement devices and fluid entry into and exit from a pipe. These losses represent special cases and are not included in the tables.Equivalent Grades, Alloy Steel,Mild Steel,Stainless steel Ashtapad is India's one of the leading steel flanges manufacture specialize in din flanges steel flanges asme flanges stainless flanges and others products Stainless steel, Carbon steel, Alloy steel, Nickel, Other Ferrous & Non Ferrous metals In Shape Of Pipes, Tubes, Pipe Fittings, Flanges, Fasteners Etc.Equivalent GradesMaterial S355 Steel Properties, Comparison, Equivalent DIN EN 1.2842 Steel 90MnCrV8 Material Equivalent, Datasheet, Properties, Composition European EN Standards BSI and DIN Standards Surface Finish1U 1C 1E 1D 1X 1G 2A 2H 2C 2D 2E 2B 2G 2P 2R 2Q
