Sir agar formula 1 me CFM dekha jaye Airflow CFM 80 hai to usse Kya samajha jaye ek hints chahiye tha Isliye ki Mera jehan iske baad TR ke baare me soch Raha hai.
Sir G very good explain ...Sir kia app apni video ki Playlist bana saktai hai koi bhi 2 choti example lai kar family house and hotel jis mai ventilation duct ki design calculate karna size, supply air, exhaust air, fresh air from kitchen and toilet, Air handling unit Kitna chaia... I mean pora chota project explain karai basic se end taak...it will be really help to understand complete project..
Sir G i am following and learning from ur video more then 2 years ...U really explained very good and especiallay in a easy way. It really help a lot to learn from your channel. I was waiting a long time when u will explain CFM per room and luckily I have learned today also ...Many many thanks ...Now I hope to see some projects example of ventilation as u said inshallah....
FCU selects cooling/heating load capacity and then calculates airflow accordingly. Alone air ventilation formula isn't sufficient to select an FCU (Fan Coil Unit) for a room due to various factors.
1. Duct area calculate karna zaroori hota hai taake duct sheet ki quantity ka andaza lagaya ja sake. 2. Duct area calculate karna airflow ko maintain karne ke liye bhi important hota hai.
Sir share the table for 100 percent ventilation for a storage hall I did not find any table having ACH for storage hall, Ashrae Table 6.1 shares only cfm per ft2, when we calculate CFM using only this total number of CFM value comes very low which is not acceptable for very large hall
Sir G I need also your whatsapp number. please make also whatsapp group, where u can share also some topics of heating ventilation air conditioning system...Whatsapp is also easy platform to contact or discuss from all participants views.

Insha'Allah I will work on your comments
Sir You said 7.2 instead of 7.5
And if 7.5 CFM/person is correct then I think the no 3 formula need to be correct...if am wrong please correct me
@@abulfaraz66877.5 value in 3rd formula is ok
Assalam o Allikum...can you plz share the ACH table used for formula # 1...
W.Salam, available on Google search
@@TanweerAhmed JazakALLAH...you have been extreamly helpful in transfering MEP knowledge to others...May ALLAH SWT bless you for this
We can use this formula to select fcu for a room?
FCU selects cooling/heating load capacity and then calculates airflow accordingly. Alone air ventilation formula isn't sufficient to select an FCU (Fan Coil Unit) for a room due to various factors.
Sir electrical services ki video bnaye..
Ok noted
Sir, Dry types connection 2.5×2.5×4" ( fire Fighting kaha use hota hai ye kya hai plz reply fast)
It is hose connection valves with outlet 2.5 inches x outlet 2.5 inches x inlet 4 inches pipe connection. Dry type means used in cold area.
Sir Air change karney ka method kya hoga usually We do not open door in AC room
If you have single split AC then you should add through small fan or window etc. If supply air is from AHU then fresh air will be added there.
How yo know about grill size
Basic term is airflow (CFM) for grill and then size with different factors like NC, Velocity pressure, Neg. Static pressure, etc,
Assalamualaikum sir ham duct ka area ko nikalne ki kya jaroorat padti hai aur iska Kya kaam padtaa hai.
1. Duct area calculate karna zaroori hota hai taake duct sheet ki quantity ka andaza lagaya ja sake.
2. Duct area calculate karna airflow ko maintain karne ke liye bhi important hota hai.

Let me check
Sir Very informative and to the point video
Any wahstap number through which we can reach you?
Thank you
