Ashrae Duct Fitting Database Version 60005 Jun 2026

ΔP=Co×Pvcap delta cap P equals cap C sub o cross cap P sub v Pvcap P sub v represents velocity pressure (

) for each fitting based on geometry, flow rates, and Reynolds numbers. The total pressure loss ( ΔPcap delta cap P ) is calculated using the formula:

: Enter the volumetric flow rate (CFM or L/s) and velocity targets. The software automatically computes the corresponding velocity pressures.

: It contains loss coefficient tables for over 200 types of fittings, including round, rectangular, and flat oval designs. ashrae duct fitting database version 60005

For engineers looking to ensure their designs are precise in 2026, subscribing to the latest ASHRAE Duct Fitting Database is a necessary step.

: Corrected and restored missing compiled database tables ( *.mdb formats) to maintain consistency with the master text file.

Fittings are cataloged using a strict alphanumeric system. The prefix identifies the shape and role of the system component: ΔP=Co×Pvcap delta cap P equals cap C sub

If you need to dive deeper into deploying this version for your current design workflow, let me know.

This article explores the capabilities of the , particularly focusing on the advancements found in modern versions like 6.00.05 . What is the ASHRAE Duct Fitting Database?

Added round straight ducts for constant equal friction (CD11-4) and velocity-limited designs (CD11-3), as well as flexible elbows with specific r/D ratios (CD3-22, CD3-23). : It contains loss coefficient tables for over

: Users can enter specific flow rates and fitting dimensions to instantly obtain loss coefficient data and associated pressure losses.

Version 6.00.05 introduced several key improvements over previous iterations. According to ASHRAE, the enhancements include an integrated database; fully available input, output, calculations, and table data properties; and easily viewable calculations that update in real time.

) for hundreds of fitting geometries. The dynamic pressure loss ( ) for any given fitting is calculated using the formula:
