To calculate the cubic feet in a sample 1-foot length of this duct, convert the cross-sectional area to square feet using the conversion factor: 36 square inches x 0.0069 square feet per square inch = 0.25 squar
In Revit most duct fittings families expose an Area value for the cross sectional area of the fitting. This is only the case for fixed-seze fittings however. Parametric duct fittings do not expose this value directly in the family. Parametric duct ...
The cubic feet per minute (CFM) of a gas describes its volumetric flow rate through a pipe or vent. The volumetric flow is a good measure of how much gas goes through the system, but it isn't the clearest way of picturing how quickly it moves. To picture this speed, calculate the li...
It is not recommended to vent with more than two elbows. The installation instructions for your model should include a formula to calculate the distance you need. Ensure that the duct is long enough to extend outdoors, preventing the recirculation of air back into the kitchen. Learn more about...

If you want a homemade wind generator using a car alternator setup, you can place the alternator and the setup alongside it in a windy area or apply a large amount of wind to it to see if it generates power. Other possible sources of energy include a paddle that you can connect to th...
measuring the cross-sectional area A of the pipe, duct or riverbed. The second quantity is the velocity v of the air or water at that point. You may have to measure this directly, but in the case of water flowing through a pipe, you can calculate it using Poiseuille's...
Hello Ansys community,I have the geometry STL file and I am going to convert it to solid geometry by SpaceClaim software and get an Export in STEP format from it. First, I Imported the STL file in SpaceClaim, then I selected the Auto-Skin option from the
How to Calculate Room CFM – An Example You can check this example with the CFM Calculator above. Try various inputs to see how the data changes as you change room size and necessary ACH – air changes per hour. Room size: 400 square feet with 10-foot ceilings, or 4,000 cubic feet ...
