Class 5 | Elite fire Hydrant Network Calculations

[@mushthaq123]

if we have a Fire Hydrant network connected to the Sprinkler system in a building which is combined system having Fire hose cabinet. Is it not possible to make it together, Like considering one extreme hydrant and one hose cabinet and set of sprinkler in the hydraulic area

Hi Mr. Irfan, if we have hydrant network which is connected to sprinkler system and have class 2 hose cabinet so how we consider

I got your email and I replied. Pls do check and confirm

May I know the Maximum flow for Fire Monitor

[@JNC2014]

I have seen some project they use 100 psi residual pressure and 3 active hydrant total of 1500 gpm. Is there special case to use 100 psi residual pressure for hydrant?

[@irfancfps]

Yes u r right. Most of the contractors consider 2 remotest hydrants and 100 psi min at remotest hydrant. However as per nfpa 24, only 20 psi is enough at the remotest hydrants while performing the calculations. Regarding no. of hydrants to be considered, we can consider one hydrant for maximum 1500 gpm and run the calculations. 100 psi at remotest hydrant can be considered in special cases like for industrial plants etc but depends on the local codes and regulations

@@irfancfps Thanks a lot for your reply and effort. I'm trying to find the required number of active hydrant from NFPA 1 and NFPA 24 but it doesn't mention about it. Or is it the designer who will decide how many hydrant will be active for the calculation.

[@mushthaq123]

Yes you are right. This is considered industrial fire fighting as per Saudi aramco

[@mushthaq123]

The red hydrant flow is maximum 500 gpm

[@mushthaq123]

Based on fire flow requirements we consider like that

Thanks sir for making video on demand base .. 1. Sir can you make one more video on FF... 2. One pump room is supplying water to 3 to 4 restaurants how can we do this calculation sir.. If U provide me one video it's better for me sir ... Thanks for making video on hydrants..

Thank you for your feedback and queries. If u could share me the architectural dwg for those restaurants I could review and let u know . [e-mail]

Kindly provide the clause of minimum residual pressure of hydrant from NFPA24

[@irfancfps]

Please refer NFPA 24 (2019 Ed), D.4 Classification of hydrants

[@MohamedEmad-sj4ix]

@@irfancfps This clause is for public hydrant or private hydrant?

[@irfancfps]

@@MohamedEmad-sj4ix Specific to hydrant. Applicable for both. You can refer NFPA 24.
