Let me give some more details:
- area is approx. 2500 m2 single space
- the ocupancy classification is OH-I
- spr type is SU
- the alternative sprinklers are K=79 and K=81 (metric)
- the Hyd Calc is done for K=79,
- piping already installed, just want to use two different types of
sprinklers in the same roof
Apart from this particular case, can there be any generally
applicable rule?
