Thankful for your response
RE: question in hydraulic calculation
That's not always the case. For a building with a LH or OH-1 or OH-2 discharge density combined with a Class I standpipe, the standpipe can be more hydraulically demanding. I currently have a sprinklered 27 high rise on my desk with 3 standpipes. The 1,000 GPM @ 100 PSIG at the highest floor is far more demanding than any on the OH-1 or LH discharge densities.
RE: question in hydraulic calculation
Yes it is true and most of the cases standpipe system is more demanding compared with sprinkler system, my statement is only to clarify the question of zicooo regarding on combining the standpipe system and sprinkler system in calculation, although, NFPA also states that if the building is partially sprinklered, you must combined the two system in order to get the system demand.
