Enter Duct Airflow (CFM), Duct Velocity (FPM), Duct Length and the number of bends. Online Ductulator Free Duct Size Calculator. Ductulator calculats duct dimensions using equal friction method or velocity method. It calculates both rectangular and round duct dimensions.

Air duct also termed as ductulator is a passage that is used to provide fresh air into rooms, buildings etc.

Air ducts may be in circular, square and in rectangular shapes. This Ductulator uses the Colebrook equation to calculate the smallest duct size acceptable for the selected friction rate and duct type that stays within the selected ACCA Manual D recommended velocities. If selecte Flexible roughness is 0. The Velocity Reduction Method can be used when sizing air ducts. Friction Loss Calculator for Flexible Ducts. The method can be summarized to.

THREE STEPS TO SIZING AIR DUCTS.

Calculate the CFM needed for each room HOW: Perform a whole house and room-by-room load calculation (Manual J). How to calculate CFM and duct size? How do you calculate duct size? Local Contractors Estimates.

Put Your Logo on a Ductulator Wheel Chart or Ductulator. Sizing of air duct can be done using Velocity Metho Constant Pressure Loss Method and Static Pressure Recovery Method. Convert Round Duct Size to Rectangular Duct Size for equivelant airflow. This is a handy tool when deciding what size duct you want to use for your application. Read computed values for Duct Diameter (inches) and Velocity (FPM).

Download Duct Calculator for free. Duct Calculator is a powerful tool that provides access to duct calculation and sizing capabilities either as a standalone Windows program or from within the Autodesk Building Mechanical design environment. Duct work that is an incorrect size can cause unnecessary noise, increased energy costs and lower air quality.

Another important unit to know is the friction loss rate of your ducts. This helps your contractor determine the static pressure for your unit throughout the length of your ducts—another size measurement that affects the overall air flow from your system. This app allows HVAC engineers to determine the smallest size Thermaflex duct recommended for the installation at han based on the project’s specific volume and friction loss.

This handy little device allows you to size your new air.
