Easy Way to Design Duct for HVAC System (Sizing & Layout)

I share how to design duct using a simple layout as example. I explain the design methods, design parameters and how to use the friction loss chart to find duct sizes. I also share some of the important considerations when designing a duct system.

Thank you for taking the time to make this presentation 👍🏽

It was definitely a very explanatory video. We would like to see a presentation where the fittings connection rules are explained in more detail with SMACNA and ASHRAE references.

Hope you could show examples for the other two methods in duct sizing:- static regain and constant velocity. Do like to share this 'equal friction method' video please.

is height of the duct same in everyroom if the height of the ceiling is same in every room.Or do we need to decrease the height according to cfm

Could you provide us with an excel sheet log of Ashre and Smanca codes if you have one please
Thank you
