Ashrae Duct Fitting Database Version 60005 Free -

Find the pressure loss for a 45-degree round elbow, 12-inch diameter, radius-to-diameter ratio (R/D) = 1.0, at 2000 CFM.

Step 1: Navigate the Database Open the table named FittingLossData. Use the form view. Filter by "Elbow, 45 deg, Round."

Step 2: Find the Loss Coefficient (Co) Version 60005 will return a Co of 0.15 (for R/D=1.0, smooth).

Step 3: Calculate Velocity (V) Area of 12" round = 0.785 sq ft. Velocity (FPM) = 2000 CFM / 0.785 ft² = 2547 FPM ashrae duct fitting database version 60005 free

Step 4: Calculate Velocity Pressure (VP) VP = (V / 4005)² VP = (2547 / 4005)² = (0.636)² = 0.404 in. w.g.

Step 5: Calculate Fitting Loss (ΔP) ΔP = Co * VP ΔP = 0.15 * 0.404 = 0.0606 inches of water gauge

Without Version 60005, you would have to guess the Co (often leading to 0.1 or 0.2 errors). A 0.06" error across 50 fittings ruins your fan selection. Find the pressure loss for a 45-degree round

The DFDB is a digital library of pressure loss (loss coefficient) data for hundreds of HVAC duct fittings — elbows, tees, transitions, takeoffs, dampers, and more. It is based on ASHRAE Fundamentals Handbook, Chapter 34 (Duct Design) and ASHRAE Research Project RP-1493.
