Sir,aap nay sirf aik dafa main line reduce ki us mein say 800 less Kar k 2800 banaya,agay jesay jesay branches nikalti Jaien gi,usi tarha third main or pher 4th main reduce Hu Kar nai banay gi Kiya. Jaha jaha say branch less Hu gi waha say agli main reduce Hu Kar agay nai jai gi kya. Guide please Thanks
Tanx, your video very useful. I have some doubt MC-quay software - equivalent 12,but you take 14 how did you take can you explain me sir ? After now I'm Dubai, how I choose this kind of 75 %25 ATM 1 . I'm waiting for reply
Thanks for uploading..I have a query can u make a video on Trouser Duct..what parameters we have to take while design trouser duct..Kindly upload..Thanks
Sir sometimes, By equal friction method the velocity goes above 1200 FPM ... Then please suggest us that upto what velocity we can use equal friction method..?
sir how much gap we will give in between two diffuser ? u placed two diffuser in dinning room without mentioning that exactly how much gap we should give.i mean how can we place two diffuser without considering air throw in between them.. sir plz explain use of air flow data for evaluating exact gap dimension b/w two diffuser and size of diffuser aswell ...
The distance between the two diffusers should be even based on the layout. Different factor need to be considered while considering the location of the diffuser such as the furniture layout and based on the area and experience you should decide.
thumb rule : 1 ton (400 cfm ) for every 125 sqft. .EXAMPLE : Calculate room size : 12 ft length x 6ft width = 132 sq.ft = 1.056 ton = 400 cfm approx. GOOD LUCK
Sir AMK can you send the completed Autocad drawing you used on this tutorial, would appreciate also if you cand send me necessary references for Duct sizing calculation and link for the software
Depending upon the CFM Airflow the size of the Diffuser are provided by the manufacturer. It is the job of the engineer to check in the catalog and select as per the requirement. Usually it is selected in such a way that by making an standing size of the different with in the Airflow range.
Visit HVAC sites asuch as possible n c how chillers, pumps, ahu, pipe n duct routing, dampers etc are installed. Take pen copy n note line diagram n ask people working in the plant room.
Sir.... in the Beginning you have asked to set the parameter to 75°F 50%RH But later you changed it to 68°F STP.... how should we select it and how does it vary our calculation....please Explain
2 x (w + h) x l is the area of the straight duct. now if the size are reducers then you need to modify the same formula accordingly. For example if you have different width and height of the duct then. 2 x (w1+w2/2) + (h1+h2/2) x l
Ismey kuch baate aaplog hide kar dete ho jaise equivalent 11 inch aaya to aapne duct size 14 inch x 8 inch Kiya isko bataiye kaise Aapne ye size choos Kiya ...Kya ye Sahi hai ..Andaz se liya ye kaise pls explain

For duct sizing I also understand we need to maintain aspect ratio ( width : depth) of 1 to 4. Are we maintaining the same?
Sir aap jo duct size dal rahe ho jaise 14*8 wo kaise approx dal diya ?? Kuch bhi dal sakte h kya?? 14*8 hi kyu ?? 12-13-14 kyu nahi ??
Pvc ke pipe ke liyeh headloss bataona sir plzzz
Sir I m watching your post, very useful.Could you explain heating and cooling calculation in Revit .software
please make videos on friction loss in reducer, offset, cooling coil, damper etc
Sir the equivalent diameter, how you are converting into Length and Width??
Use HVAC DUCT SIZER... you can understand
Are you using .1 equal to 100 mm
I am right ?
Plz make video on equivalent diameter v/s equivalent cross sectional area approach with example
what is the consideration of submitting the assumption value of duct width in main and branch lines..
Sir plz make a video on different between diffuser, register and grill
Very useful
Thank You Daood. Keep watching.

How to take print in autocad
I kindly request please make videos regarding viewports, template in autocad
Thank you
You have to give the information about length of reducer that you get and length of shoe coller
how to take approximate duct size can we take same as equivalent dia
Yes you can start with equivalent dia
Sir sometimes, By equal friction method the velocity goes above 1200 FPM ... Then please suggest us that upto what velocity we can use equal friction method..?
For low pressure duct design.
Main duct can be sized upto 2000 FPM
How can do sizing for return duct ?
sir how much gap we will give in between two diffuser ?
u placed two diffuser in dinning room without mentioning that exactly how much gap we should give.i mean how can we place two diffuser without considering air throw in between them.. sir plz explain use of air flow data for evaluating exact gap dimension b/w two diffuser and size of diffuser aswell ...
The distance between the two diffusers should be even based on the layout.
Different factor need to be considered while considering the location of the diffuser such as the furniture layout and based on the area and experience you should decide.
sir plz make a video on placement of diffuser by considering these factors....and also how to find the size of plenum box..
What is the basis of assuming CFMs in various rooms.
thumb rule : 1 ton (400 cfm ) for every 125 sqft. .EXAMPLE : Calculate room size : 12 ft length x 6ft width = 132 sq.ft = 1.056 ton = 400 cfm approx. GOOD LUCK

Depending upon the CFM Airflow the size of the Diffuser are provided by the manufacturer.
It is the job of the engineer to check in the catalog and select as per the requirement.
Usually it is selected in such a way that by making an standing size of the different with in the Airflow range.
Visit HVAC sites asuch as possible n c how chillers, pumps, ahu, pipe n duct routing, dampers etc are installed. Take pen copy n note line diagram n ask people working in the plant room.
plz give me the link to download that design tool duct sizer 6.4 software
Sir.... in the Beginning you have asked to set the parameter to 75°F 50%RH But later you changed it to 68°F STP.... how should we select it and how does it vary our calculation....please Explain
It doesn't affect the duct size check it yourself in duct sizer
hello sir can i contact with you?
Sir,
How to find out length of bend in duct...???
Kindly explain...????
2 x (w + h) x l is the area of the straight duct.
now if the size are reducers then you need to modify the same formula accordingly. For example if you have different width and height of the duct then.
2 x (w1+w2/2) + (h1+h2/2) x l
