Duct Calculator Elite is an industry leading tool designed to simplify solving everyday problems for HVAC professionals. This app allows users to calculate the duct size velocity pressure drop and flow rate for ductwork in HVAC applications.

Duct Calculator Elite features a highly intuitive interface which allows the user to easily enter values with precision (without the use of cumbersome "slider" controls).

In "Duct Size by Airflow" mode the calculator allows users set airflow and either velocity or friction(Pressure Drop) and the calculator solves for round and rectangular duct sizes. Aspect ratio of the rectangular duct can also be specified.

In "Duct Size by Dimension" mode users can enter either a round duct diameter or rectangular duct height and width. In addition users can lock airflow velocity or friction and solve for the other variables.

-In "Pressure Drop" mode users can convert between duct length pressure drop and friction values. This allows users to quickly determine exact pressure drop of a given installation or calculate the max duct length that can be used to maintain desired pressure drop. This feature compliments the two duct sizing calculators.

Duct Calculator Elite provides users with a wide variety of setting including:
-Duct Dimensional Units (Inches Centimeters or Millimeters)
-Airflow Units (Cubic Feet per Minute Cubic Feet per Second Cubic Meters per Second or Liters per Second)
-Velocity Units (Feet per Second Feet per Minute or Meters per Second)
-Pressure Loss Units (Inches of Water per 100 ft or Pascals per Meter)
-Duct Material (Aluminum Concrete Fibrous Glass Duct Liner Flexible Duct-Metallic Galvanized Steel PVC Plastic Pipe Smooth Liner Spiral Steel or Uncoated Carbon Steel)
-Air Temperature (Fahrenheit Celsius or Kelvin)
-Elevation (Feet or Meters)

The Duct Calculator Elite solver uses friction loss equations contained in 2009 ASHRAE Handbook - Fundamentals. The next time you go to a meeting or out to the field leave your Ductulator at home you`ll have everything you need right on your device.
