Ashrae Duct Fitting — Database Version. 6.00.05 Fixed

The ASHRAE Duct Fitting Database is a comprehensive digital catalog of resistance coefficients (K‑values) for hundreds of standard duct fittings. It includes detailed loss coefficient tables for more than , each accompanied by a clear pictorial outline. For any given fitting, engineers enter the flow rate and relevant dimensional data, and the software instantly returns the loss coefficient along with the associated pressure drop.

Version 6.00.05 built on these changes by integrating the database and adding real‑time calculation capabilities. For the mobile app, subsequent updates (Version 6.1) refined specific fittings such as SR7‑2, SR7‑3, SR7‑14, SR7‑15, SR7‑16, and SR7‑17. ashrae duct fitting database version. 6.00.05

Understanding the ASHRAE Duct Fitting Database Version 6.00.05

Version 6.00.05 of the is a specialized software tool developed in accordance with the ASHRAE Fundamentals Handbook and the ASHRAE HVAC Duct Fitting Database (RP-1493). It provides engineers, designers, and HVAC professionals with validated loss coefficients ((C) or (K) factors) for a wide range of duct fittings used in air distribution systems. The ASHRAE Duct Fitting Database is a comprehensive

The is a specialized engineering software tool used to calculate pressure losses for various HVAC duct fittings. It provides authoritative loss coefficient data based on the ASHRAE Handbook—Fundamentals. Core Functionality

Additionally, ASHRAE announced that support for version 5.x will cease in December 2024, meaning no more technical assistance or errata.

Version 6.00.05 is not just an update; it's a significant overhaul. The official documentation for version 6.0 highlights an and a user interface where inputs, outputs, calculations, and table properties are fully available , with calculations that update in real-time .
