HVAC Buddy Duct Calc - Fast, Powerful Duct analysis that is always with you!The best and number one selling duct sizing tool for Android devices with over one thousand downloads. For less than the cost of a cardboard wheel ductulator always have a fast, accurate way to analyze ducts for design (by Airflow) or existing installations (by Size).
Airflow Tab
• Calc decimal & rounded sizes for any aspect ratio
• Solve for Volume, Aspect Ratio, Friction, or Velocity
Size Tab
• Calc Friction and Velocity given duct size
Settings Tab:
• Enter various units - Airflow (cfm, m3/s, l/s, m3/hr) Friction (in/100', Pa/30m), Duct Sizing (in, cm), Velocity (ft/min, m/s)
• Define standard air - Altitude (ft, meter), Temperature (Fahrenheit, Celsius), Relative Humidity (pct)
• Displays calculated Kinematic Viscosity (ft2/s) and Specific Volume (ft3/lb)
Material Types:
• PVC
• Aluminum
• Galvanized Steel
• Spiral Steel
• Smooth Liner
• Fiber Liner
• Flex Duct
Duct Shapes:
• Round
• Rectangular
• Oval
Duct Sizing
• Round to Even Units
• Round to Odd Units
Calculations are based on friction loss equations in the ASHRAE Handbook of Fundamentals 2009.
With respect to the review questioning Accuracy:
-----------------------------------------
Calculations have been verified against ASHRAE fundamentals and several other references. There are more input criteria (such as duct material) than velocity, friction, and size mentioned in the review which the reviewer may not have taken into consideration. Use the Support email link for any questions or concerns.
