Dear in ur earlier value u r considering mean gpm like 20100 gpm (overhhead tank) and undrground tank capacity was 1207296 gpm so it is not 1/3 of undrground tank capacity. Which we have to follow this one or that one with peak factor method . Thansk
How did u know 0.33 bar pressure for each floor without booster pump? Any formula ot refrence, somewhere u me tioned 0.433psi per feet and here 0.33 bar per floor. Plz clarify
Assalamu alaikkum Sir , you send me Reference drawing and support details and AHU plenum design also CAD file could you share me sir ...Im working in UAE so if you send drawing, will be use for me sir
Thanks bro. Total building ki requiremnt kounsi hugi hot+cold ya total qty. agar ham ne tabk select krni he to hot+ cold jama krke sumup kre ya total load.
allowable pressure drop calculated 2.46 psi, approximated 2.5 psi/100 ft length.on the video you explained for 18.48 gpm with the table of 1 1/4 but in the table you added 1 1/2", in that sense its falling below the allowable friction loss of 2.5 psi.meaning, we have to contain the pressure loss below the alloeable friction loss, not 5 psi /100 feet length you early mentioned. But on 206.4 wsfu, corresponding 48.09 gpm the pressure drop value exceed 2.5 psi, and itvwas 2.71 psi though it s less than 5 psi.. Clarify me, that pressure drop in this case must below 2.5 psi/100 ' , From our allowable friction loss calculation or thumb rule of below 5 psi/100'...
You can follow tables give in SMACNA, it depends on pressure class,duct sheet gauge used for duct. You can watch this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PeEilQztW2E.htmlsi=tk9QV71_LoB7dWNB
THANK YOU SIR FOR YOUR VIDEO I HAVE A QUESTION FOR RECTANGULAR DUCT REDUCER FORMULA AFTER CALCULATE THE w+h , THE w1x h1 NO NEED TO ADD INTO THE CALCULATION FORMULA? A=1.92M2 is complete size of this reducer? Thanks
Thank you for this informative video. any rules for number of flexible connections? what is the height of the box? limited to false celing height is a point but any relation to W and L of the box? Dia of Flex? can you kindly clarify these things? Thx in advance.
By heat load calculation & selection of AC unit. I only assume this CFM, to explain selection of grill. different types of rooms may have different CFM, as per their use and project conditions.
And sir kindly provide the link below in your videos so we can download or can get the tables of standards Ashre Grill table etc.... Because its very clear and HD quality with you please sir 🙏 waiting for your response hope so that you will reply as soon as possible lot's of love from Abdul Ghaffar ❤❤❤❤❤
With most respect 🙏 fully sir can you provide your Gmail or any other contact details to contact you for some points please I will be awaiting for your reply.
Good afternoon sir its very impressive and very helpful ❤ always specially thanks to you for this grate effort may Allah bless you and rewards your more and more then a thinking ❤❤
We know NC level for 625 CFM is 26, Then we calculated by interpolation for 75 CFM to know NC level for 700 CFM. if you will watch carefully this vedio and try to understand the calculation, it is very easy, but to understand the concept,please watch again & again.
In your 500pa example, can you use 26 gauge for the 12 inch height and 24 gauge for the 36 inch width provided that this duct is made from 4 parts? I don’t see where in SMACHNA that it says you must use the same gauge for the same piece of duct. Thx in Advance
