Your video was excellent, I really liked it, but in the 5th minute you said that we should unify our dimensions, for example, we attack the height first and then the width, but I think that in many cases when you going to install the ducts, you will always find many restrictions by height and not by width . I tell you this comment because it is very easy to find a small space between the ceilings and next floor, thanks, best regards. Also, remenber that you must to think in diffusors´s dimensions. Thaks, best regards..
Thanks for your advice. I agree the restriction is usually the height not the width. Where or what resources can I find/use in order to learn best on supply and return grille/register sizing and location?
Nice video sir but one thing is the width of the duct can maintain below the equivalent diameter then only we can get near to W & H.....And see in your video there is no reduction of the width sir and its thought only not to discourage sir Thank you
In supermarkets, we can see spiral flat oval ducts of uniform size from machine till the end. How they are selected. How can we ensure supply from all terminals? I am asking for grills fixed on duct itself. Curved/universal grilles
MEP WORK: You guys are great, thank you very much!
Why did you keep 22 inc width as constant throughout. And there is no reduction in width required when it reduces from 1000 to 500cfm?
Dear very nicely you have explained and how to design the ducting with McQuay software. keep doing
We expect more from your channel.. your website is awesome..
Thank you brother

Very nice video but why you choose 22 for main duct at the beginning, you can choose other number also like 20,30,12 etc.... can you explain please
Sir you have any link for download mcquay
Thanks for making Tutorials in English.. Please keep it up.. 🙌🙌🙌
Thank you .. Ok I will
Sir, make a video of Oval duct design in autocad and calculation of oval duct.
Hello sir, we get w and L . How about length?
Please can not make download for duct size program (Mcquay) please help me
Nice video sir but one thing is the width of the duct can maintain below the equivalent diameter then only we can get near to W & H.....And see in your video there is no reduction of the width sir and its thought only not to discourage sir
Thank you

Sir plees help me and give me some time pleeeeeeeees teach mee
But the friction rate is too low, it should be 0.08 to 0.1. Could you please explain friction factor?
Any software in mobile application
Thank y so much .. clear and easy
Hi, can you make a video explaining the calculated friction factor, velocity pressure and head loss above? Thank you.
friction loss is calculated according to the accepted air flow velcity in the space.
Pls make videos other software also related to HVAC
thank you so much
THANKS
can you please make a video Step By Step external static pressure calculation
Ok soon
Thanks buddy
The first branch taken 1500cfm. 4000-1500=2500. How come 3000 after 1st branch.
I don't understand. Please explain.
Its 500+500 not 1000+500. Each grill required cfm is 500.
So 500 +500
Can u pls give the tutorial of Hap software
nice...very useful
great
For my practice
GREAT

Please, someone has this video in Spanish? my English is not so good, thanks
Dude you made a mistake, calculated total diffuser out put CFM is 6000 CFM main duct size is wrong.
actually yeah. it suppose to be 6000 cfm
no its 4000 cfm each diffuser will take 500 cfm
