Hydraulic Calculations For Fire Sprinkler Systems

[@JWu-jt7fz]

Best explanation I've seen so far! Thank you kind sir

[@chesterco9586]

Thank you sir for this knowledge, very well clearly expalined.

[@mikerod5396]

What is the pipe for those pipes not within the design area? Do those pipe runs need to match the pipe diameters of the pipe within the design area? This pipe layout is interesting.

[@MartinKryekurti]

Nice video guys. Had a question , What does : Pressure at hydraulic junction point shall balance within .5psi mean ? Is it times .5psi ? or divine .... ?

[@andisuharto9728]

tanks a lot , Mr. Harland

[@dennisregalado367]

Thank you, clear explanation and knowledgeable. Do you conduct actual training,

[@h.machaconmechanicalengine9300]

I don't conduct training because I am very busy and I am doing these videos on my free time. NFPA is conducting training on these topics. You can also read the different NFPA Standards on their website. Check out their website.

[@leonciogarcia9989]

will they upgrade the pump or install a separate system for this expansion, or the capacity of the pump is enough , thank you sir for the informative presentation.

Refer to our video tutorial City Water Supply Versus Fire Sprinkler Demand

[@andresmata3727]

Hi sir great video. Could you please tell me how do you determine the largest area covered by any sprinkler in the design area? (Point 4).

[@icutoo2699]

It's in NFPA 13, the most hydraulilly demand, usually the farest and highest from the water supply from the base of the building riser.

[@mariomabaga2014]

nicely and clearly explained sir..

[@andisuharto9728]

Mr. Harland, may I ask, at 8.49 minutes it was stated that there were 2 Tees, but in the end why did it say only 1 tee (10) with a 2 inc pipe schedule 40. or not 2 x 10, forgive me if I'm wrong ,explanation please

[@andisuharto9728]

oh sorry, it turns out I was wrong careless

[@ginoafricano8831]

Hello sir, may i ask is the formula for pressure drop applicable also in Fire Hose Discharge?

[@h.machaconmechanicalengine9300]

Yes

[@warunakarunarathne1523]

What is the recommended software to draw the design and simulation

[@h.machaconmechanicalengine1187]

There are lot of commercial software available in the market. Most engineering firms use HASS Fire Sprinkler Hydraulic Analysis Software!

[@h.machaconmechanicalengine9300]

There are several available in the market.

[@zaccblack103]

Sir, when doing hydraulic analysis of combined systems, should you include the fire hose stations in the analysis, i.e., 100 gpm, 65 psi?

[@icutoo2699]

When doing calculations check with the AHJ on how to perform them. Each AHJ may have different rules. You need to read the chapter in NFPA 14 and make sure your using the correct edition that complies with your local code requirements. Your local code could be different from NFPA 14 & 13. You alway need to read and re-check since they do make changes to the standards.

[@aivencanales9187]

hi sir, how did you get 129.87 ft2 in item no. 4?

[@h.machaconmechanicalengine9300]

From the layout, compare the area covered by each sprinkler within the design area

[@The08206]

hi, why did you get only 1500ft2 for calculation. why we cant take more than 1500ft2?

[@icutoo2699]

Typically you want the most economical system, smallest pipe size, smallest pump. The larger the design area the higher the water demand and therefore a more expensive sprinkler system. 1,500 sq.ft. is the smallest area on the graph.

[@The08206]

Thanks for your response. so when we can consider more than 1500 ft2 area for calculation? I mean which industry. @@icutoo2699

[@ronaldreybasillote6498]

Good day sir.. thank you for the clear explanation... can i ask the price of your "computer program hydraulic calculations" thanks and God bless sir

[@h.machaconmechanicalengine1187]

I suggest you purchase commercially available Fire Sprinkler Hydraulic Analysis Software

[@jaypel5927]

Good video. Can you please share the slides?

[@h.machaconmechanicalengine1187]

Sure go to our website www.hmachaconengineering.ca and send me your email

[@zaccblack103]

Are you a Filipino, Sir?

[@rickyparagas]

Pilipino ba kayo sir?

[@ethinkgroup8492]

Hi Sir Harland, your explanation is so good. We are a startup looking forward to benefit students in India with your expertise. It would be a privilege if you would partner with us. Can you share your email so I can send details. Thank you

[@h.machaconmechanicalengine9300]

My email is [e-mail]. You can also go to my company website www.hmachaconengineering.ca and then there you can message me directly

[@ethinkgroup8492]

Hi Sir, sent mail to you

[@raplabrador]

Hi Sir Harland, may we invite you to conduct a technical presentation to our Mechanical Engg organization chapter meetings here in the Philippines through online e.g. zoom?
