This is the MEP tutorial video about "Natural Gas Pipe Sizing Longest Length Method NFPA 54" in Urdu/Hindi. Here I have explained, how to Sizing Natural Gas Piping Systems with the natural gas pipe sizing equation/natural gas length design method. It is also important for HVAC/MEP technical staff. Here sharing my experience and knowledge that will be helpful for learning & growing for Engineers & Technical persons. If you found anything which is inappropriate then convey it in the comments for my information and rectification in the future.
