@@successengineeringofficial7742 for example, supply is 100 lps fa is 20 lps so return is 80 lps right, so room will have excess 20 lps right, where it will go?
Dear Anjum Arshi Thanks for your comments and thank you for watching my video, please subscribe my channel and share my video with your friends. actually as per thumb rule hum log tonnage calculate karne ke liye ek formula use karte hai. TR = AREA X FACTOR FACTOR IS 0.07 FOR RESIDENTIAL, 0.08 FOR COMMERCIAL AND 0.09 FOR INDUSTRIAL BUILDING KE LIYE USE KARTE HAIN FOR EXAMPLE IF YOUR AREA = 14 M2 THEN TR = AREA X FACTOR = 14 X 0.07 = 0.98 APPROXIMATE 1 (FOR RESIDENTIAL BUILDING) SO 1 TON = 400 CFM HOTA HAI (AS PER RULE OF THUMB) SO SUPPLY AIR = 400 CFM RA = SA - FA (YOU CAN CALCULATE THE FRESH AIR AND PUT THAT VALUE IN THIS FORMULA THEN YOU CAN GET THE RETURN AIR RA.) PLEASE WATCH MY VDO THEN YOU CAN GET HOW TO CALCULATE FA CFM. I HOPE YOU GOT YOUR ANSWER IF ANY DOUBT PLEASE ASK ME IN THE COMMENTS.
May i know that equilent amount of FA is extracted from room ?
What do you mean

Great video pls do more videos on plumbing design
Ok Satish
i will do it
@@successengineeringofficial7742 Thanks..i will look forward for next videos...❤️
sir total cfm ka 10% nahi nikal sakte hai separate room ka ek ek kar joden ge
its depend on types of space
generally for CAV system you can take 10%of all
for vav system you can calculate for each space

actually as per thumb rule hum log tonnage calculate karne ke liye ek formula use karte hai.
TR = AREA X FACTOR
FACTOR IS 0.07 FOR RESIDENTIAL, 0.08 FOR COMMERCIAL AND 0.09 FOR INDUSTRIAL BUILDING KE LIYE USE KARTE HAIN
FOR EXAMPLE IF YOUR AREA = 14 M2
THEN TR = AREA X FACTOR = 14 X 0.07 = 0.98 APPROXIMATE 1 (FOR RESIDENTIAL BUILDING)
SO 1 TON = 400 CFM HOTA HAI (AS PER RULE OF THUMB)
SO SUPPLY AIR = 400 CFM
RA = SA - FA (YOU CAN CALCULATE THE FRESH AIR AND PUT THAT VALUE IN THIS FORMULA THEN YOU CAN GET THE RETURN AIR RA.)

are FA CFM and outside air cfm the same ??
Yes
