This is a firefighting design tutorial video about NFPA 13 Fire Sprinkler System Design Calculation Ordinary Hazard Group 1 /fire sprinkler system design calculation/ NFPA 13 hydraulic calculations/ NFPA 13 sprinkler calculation/ NFPA 13 sprinklers / NFPA 13 sprinkler system, Ordinary Hazard Group-1, Part-1" in the Urdu/Hindi language. It is basic learning detailed information about the wet fire sprinkler system. It is also important for Firefighting/MEP technical staff and designers. Here sharing my experience and knowledge that will be helpful to learn & grow for Junior Engineers & Technical staff. If you found anything which is inappropriate then convey it in the comments for my information and rectification in the future.
