I also want to know about static pressure.. thanks for making this video sir...I also prefer your video

[@ajaydhami1784]

Sir AHU ka stetic pressure kese nikala jata h uske uper video ji

[@jayaprakasha2875]

"Jai Gurudev Dutt"
Your one of best tutor, even blind person can understand the way you explain about HVAC system. I'm being non technical person and rendering facility services. Eversince I started to watch your tutorials about HVAC system, I got enormous knowledge and confidence to handle hvac system in the absence of technician.
Thanks a ton Girish ji

[@hvac707]

Awesome sir
I learn a lot from u about hvac

Sir Fire Damper k uper ek video bnaeye please....
Types of fire Damper...
Fusible link type & actuator type...
Aur fore damper ahu k paas supply duct me use krte h ya return me...
Pls make a video on this topic...please...

Sir u r great .
Please Sir make vedio for calculation humidifier and dehumidifier ASAP

[@adnanahmadkhattak]

Sir please deliver lecture on dynamic pressure etc.
Discuss all pressures in detail please.

What are the causes if I give high external static pressure for fahu??

[@hvacparwezalam2332]

Sir chiller kitne type ka hota h video banaiye sir aapka video sab mujhe samjh me aata h chiller kitne type ka hota h ye video banaiye sir

[@noshad6409]

Thanks sir

[@happystarkidz8994]

give more example for static pressure....

[@Assalamualaikum2All]

Dear Sir,
Say AHU blower outlet 30"x35" and connected duct size 60"x20". In this case, which one we take for average?
30"x35" means 32.5"x 7.6 or, 60"x20" means 40"x 7.6

[@girishshinde]

2 x (30 + 35 ) = 130
130 ÷ 4 = 32.5
32.5 × 7.6 = 247

[@Assalamualaikum2All]

Thanks Sir,
I always following your videos and learnt a lot. I'm from Bangladesh. After recovery world from corona virus, I'll come India especially to meet you Honorable Sir.

Dear Sir … Good morning!. Koi book ka name batye jiss main centrifugal fan ki full details ho mujhe bahut jarurt hai…. Please apse request hai…

[@kusumshah-td9cg]

Sir eska matlab jaise jaise hawa aage badhegi vaise vaise static pressure v badhega??........ velocity pressure pe kya effect padega sir ?........ static pressure badhne ki vajah ki velocity pressure v decrease hoga na

[@siraj158]

Sir agar blower vertical hai to kaha lena higa

[@Behuman0627]

Sir nice explanation... Pls make a detailed video on pascal... Some Fcu & ducted units are mentioned desgined on 100 pascal !!how to check pascal etc!! Thanks in advance sir

What is difference between static pressure or absolute pressure?

[@fortunateworld041]

Sir friction k bare m bataiye kaise lete hai

[@rajtiwari5526]

sir
For any AHU fan, static pressure is selected only on basis of External static pressure???
also as AHU is having DUst filter and Coil which will create resistance i.e. Internal static pressures
Fan selection will be based only on external static pressure or we need to add internal static pressure

[@girishshinde]

Both internal, external static pressure and air quantity

[@AjayChaudhary-zr9bu]

Back press kese work krta h

[@ajas3103]

Sir how we decide blower capacity depending on static pressure and does it effect if length of duct increases

[@adnanahmadkhattak]

If we have long duct say 10 m and has louver damper in middle say point B
If i close the damper to 50 % then the static pressure at that point will increase as per your class.
What will be the effect on pressure and air flow at point c i-e the discharge.
Please guide me sir

[@pepsicoke560]

Bro there is a problem in your SP relation with motor. As static pressure rises the load on motor decreases. The motor will draw less current.

[@engineeringtrainingideas2334]

What is total pressure ? How we know the ducts status pressure design ?

Average side of fan outlet and then you multipled by 7.6 why
7.6 is duct length or distance of U meter place from fan out let
What is this 7.6
