Thank you Bro

[@naisantikerenke9707]

Why did you use 0.188 constant in calculating smoke mass flow rate?

[@mohammed5yaz985]

Wht is cps in plum temperature rise from where we get tht please explain

[@johnphilip7084]

Fire perimeter did not understand like for the corridor area is 46 m fire primeter is which valve i need to keep.

[@hayathism]

How do you balance Smoke zone positive / Negative? L

[@paulakoh4870]

Just watched you video. Quite impacting. How do I know the plume height and fire area for a fire that hadn't occured? Thanks

[@passionateengineer04]

Smoke plume height is the highest point where smoke can travel in building, usually its upto ceiling. Fire area means, the area you want to protect it from fire, where fire can occured or area protect by fire walls, fire barriers etc

[@paulakoh4870]

@@passionateengineer04 So is the fire area same as the areas of the space being considered? I mean the area of the room.

Can you send the excel sheet??

Please make a video in pharma design to keep positive pr in area with adjuscent area

smoke duct specification please

[@jaimeplanas7840]

can you show me image of the page for heat release rate as per NFPA standard?

[@cfdreseachlab5819]

Refer NFPA 92

[@Behuman0627]

what is the ACPH for pump rooms as per Asharae standards!!!

[@passionateengineer04]

Its not specify ASHRAE for pump room but they mentioned electrical equipment room, 0.06 cfm/ft2.

[@Behuman0627]

@@passionateengineer04 is there any recommended velocity for pump rooms Ducting!!!

[@weberdesign7893]

How does your building area is just 20 sq meter, similar confusion for total plume height just 3 meter only? , How do you calculate fire perimeter P, that also just 12 meter

[@johnpatricklegaspi3933]

Same question that didnt get any answer. How / where to determine the fire Perimeter anyway?

[@jaimeplanas7840]

@@johnpatricklegaspi3933 maybe from fire area P = (L + W ) 2

[@goviral568]

@@johnpatricklegaspi3933 There is No calculation , NFPA 92 states that it is assumming , you do not need to calculate Fire perimeter you just need to enter theoretical value .

[@amrelafifi4804]

fire area in not as the floor area this will increase the fan m3/s

[@passionateengineer04]

It's depends on the situation. The fire area is actually the area separated by fire rated walls if the attrium wall are fire rated and fire will not transfer from internal space like shops etc to the attrium,than only attrium area will be considered as a fire area.

How to calculate airflow smoke extract for data centre ?? if i want to design extract fan for area data centre ( 42,9 x 27 x 5 meter )

[@passionateengineer04]

Use same method, you can study NFPA 92A for further detailz

Can you please showbus how to calculate duct size of fire smoke fans ?

[@passionateengineer04]

You have to use fire rate duct.

[@passionateengineer04]

kzbin.info/www/bejne/jpmVh6BtgdZ8Z68 You can follow these steps

[@passionateengineer04]

Just put 0.04 instead lf 0.08

How to design Cargo warehouse ventilation system?

[@passionateengineer04]

Follow ANSI/ASHRAE Standard 62.1 guidelines, based on the space type, occupancy and room size. For warehouses, the ASHRAE minimum ventilation rate is 0.06 CFM per square foot. The air changes per hour (ACH) in a room. Air change rates for warehouses are typically set between 6 - 30 changes per hour. Warehouse ventilation generally involves some combination of rooftop or sidewall exhaust fans, rooftop or sidewall supply fans, rooftop gravity vents and wall louvers. These can be positioned to create different airflow patterns in the space. For example, exhaust fans can be placed along one sidewall and supply fans or louvers along the opposite wall to create a continuous crossflow pattern. Another option would be to put exhaust fans along the center roof line and supply fans on both sidewalls to bring cool air in from the sides and exhaust warm air from the ceiling. Airflow patterns should be designed to remove indoor air contaminants from the breathing zone and keep air circulating through all parts of the facility for better temperature and humidity control. In heated or air-conditioned warehouses with high ceilings, additional fans may be needed to combat air stratification, in which warm air rises to the ceiling and cooler air settles to the floor. These fans are located to promote air mixing within the room.

[@singchaentie1846]

ACH 6 to 30 are such a wide range. Are they referring to different type of warehouse? @@passionateengineer04

Tbh u know the stuff but it's useless if u can't convey it effectively...this is what I used to face with my school teachers they were also like u....☹️
