Non-Circular Duct Flow Calculations
Flow through non-circular duct calculations including incompressible flow and compressible flow for flow through an annulus, rectangular duct and general non-circular duct.
These Excel spreadsheets calculate the head loss and pressure drop for flow of a liquid through an annulus, or a rectangular duct or a general non-circular duct. There are separate worksheets to calculate pressure drop/head loss or flow rate for each of the three non-circular duct configurations. The worksheets for flow through an annulus and for flow through a rectangular duct can handle either laminar flow or turbulent flow calculations. The general non-circular duct worksheets are useable only for turbulent flow. Calculations are in U.S. units.

The worksheets for flow through an annulus and for flow through a rectangular duct can handle either laminar flow or turbulent flow calculations. The general non-circular duct worksheets are useable only for turbulent flow. Calculations are in S.I. units.
The worksheets in this Excel workbook calculate the head loss and pressure drop for flow of a gas through an annulus, or a rectangular duct, or through a general non-circular duct. There is an initial worksheet for selecting a gas and determinig its properties that are needed for the calculations. There are worksheets for calculating the flow rate or pressure drop through a rectangular duct, through an annuls, and through a general non-circular duct. For the annuls or rectangular duct calculations, the flow may be either laminar or turbulent, but for the general non-circular duct calculations turbulent flow is required. For each duct flow calculation, the choked flow conditions, which give the maximum flow rate of that gas through the duct, are calculated. This spreadsheet is set up to use U.S. units.
