Very nice video Sir. Thank you so much. Could you please also explain if possible, 1. The velocity to be considered while designing stair case duct/lift well duct and lift lobby duct. 2. Can you please explain the calculations of lift lobby exhaust. 3. Also if possible can you please explain one design of stair case duct or lift lobby/well duct and its esp calculations for fan selection. A short explanation video will also be ok. 4. Is there any insulation or coating or painting on the ducts. 5. Is the Smacna standard same applied for these ducts.(Duct guage etc). 6. Is this a fire rated duct or normal G.I. duct will be Ok. 7. In which case we use centrifugal fan and in which case we use for axial flow fans for pressurisation systems.

@@TanweerAhmed Thanks again.

[@abdelrahmanabdelmottleb905]

Thanks.. How calculate static pressure for lift well .. because there is no duct How estimate suitable static W.G

[@TanweerAhmed]

Same procedure is calculation of static pressure like g.i duct

[@abdelrahmanabdelmottleb905]

@@TanweerAhmed This results in a very small amount S.P due to the large size of the Shaft..

[@abdelrahmanabdelmottleb905]

@@TanweerAhmed sir please calculate S.P for pressurisation fan for lift case , and share with us🫸🫷

[@passionateengineer04]

I think you forgot to discuss the stack effect. The pressure is effected by stack effect. The stack effect is more pronounced in the winter. When it’s cold outside, the stack effect creates about 4 pascals of pressure for every floor of the building. In the summer, this drops to 1.5 pascals per floor.Stack effect is a result of different air densities inside and out of a building that cause the pressure distribution of air in a building to be different from that outdoors.

[@TanweerAhmed]

If you have any working about stack affect with any reference document then share with me on email. I will review and revise this video, if I satisfied with your working.

Can i hv link fr excel sheet and coses tia

Sir please koi ek project bana Dona sb calculation ke saath full hvac

[@TanweerAhmed]

It will be boring, if I will make lengthy videos. Our subject is dry therefore peoples don't like to watch.

[@MfVlogs_1]

Sir you can make short videos of one project . It's very helpful to understand . If you take one project that will be good sir you can paid for this course

Plz explain stairwell pressurisation logic , how it starts

[@TanweerAhmed]

Watch my another video "Staircase Pressurization system"

[@yuvarajkumar6095]

Sir Staircase pressurization is triggered by fire alarm panel so how many detector has to be activated for starting pressurization.

[@TanweerAhmed]

Anyone smoke detector activation then fan shall be start because fire or smoke can be happen anyone location and staircase is for throughout building.

Can u email the lift well pressurization system calculation excel file

Why ceiling not considered here?

[@TanweerAhmed]

Because lift well level is 5 floors and only one top floor has roof. If consider one floor ceiling or roof then cracking area to be 0.002 which is minor, therefore I have no considered. Moreover, I have informed this reason in this video.

[@vtv5143]

Yes u told in vedio. Thank you. Little fast , so watched once again ​@@TanweerAhmed
