[Sprinklerforum] Re: Sizing of pipe below obstructions

2022-08-23 Thread Brett Peters

Here is how I see the argument
If you pipe the sprinkler with a smaller diameter line then that sprinkler
has to be part of your hydraulic calculation (arguably you could just
switch to the sprinkler below the obstruction and remove the sprinkler
above the obstruction, as you are not required to calculate both but you
have to calculate the most demanding)
If you pipe the sprinkler with the same diameter line then there is no
additional calculations required
Piping under obstructions after design is already done it's just simpler to
pipe the additional sprinkler with the same pipe diameter but if you know
of the obstructions beforehand and include them in the initial calculations
then you could pipe them with whatever works in the calculations.

Thanks

[Sprinklerforum] Re: Sizing of pipe below obstructions

2022-08-23 Thread Fpdcdesign

  
  

  What I have is an ESFR system where i need to add a single sprinkler in 2 
locations under ducts. 23.4.4.7.3.1 states that sprinklers under obstructions 
do not need to be included in hydraulic calculations. 23.4.4.7.3.2 states that 
if the sprinklers are under obstructions are piped with the same size branch 
piping, additional calculations under obstructions are not required.I’m 
assuming that the difference is that the first one is based on one or two 
sprinklers under obstructions in isolated location. The other is if enough 
sprinklers are installed under obstructions to create an new calculation area. 
Neither really address any restrictions on pipe sizes for sprinklers under 
obstruction.
