The Ventilation System Aerodynamic Calculator is designed for calculating duct parameters necessary for the effective operation of a ventilation system. With its help, you can calculate the optimal duct sizes and determine pressure losses along the system sections. This tool will be useful for both engineers and ventilation system designers.

Calculator features:

  • Automatic or manual input for air velocity in the ducts.
  • Selection of duct material and cross-sectional shape (round, rectangular, or square).
  • Adding sections with local resistance considerations, choosing duct fittings, and specifying their characteristics.
  • Calculation of pressure losses, required and accepted duct cross-sectional area.
  • Export of calculation results in .xls format for further analysis.

Steps for using the calculator:

  1. Select the method for specifying air velocity: automatic or manual.
  2. Add the necessary duct sections by selecting the material and cross-sectional shape.
  3. Specify local resistances for each section by selecting the appropriate system elements.
  4. Input flow rate and section length parameters to perform the calculations.
  5. Click the "Calculate" button to obtain the required data for cross-sectional area, pressure, and losses.

The calculation results will include the required parameters: cross-sectional area, equivalent diameter, pressure losses, dynamic pressure, as well as local resistance parameters. This data will help you design ventilation systems correctly, ensuring their efficiency and durability.

The Ventilation System Aerodynamic Calculator will become an indispensable tool when designing ventilation systems of any scale. Use it to optimize costs and improve the performance of ventilation systems.
