For example, we could use the Tyco EC-14 extended-coverage pendent sprinkler (K=14.0) in a (Ordinary hazard group 1) restaurant service area to protect an 18' x 18' area, but here the data sheet parameters require a 49 gpm minimum discharge at 12.3 psi for the end-sprinkler. Source: Futrell Fire. Author When hydraulically calculating a light hazard sprinkler system, the design density utilized is typically 0.10 gpm/sf over a 1500 square foot (the most hydraulically demanding) area of operation. To potentially overcome this limitation, higher roof slopes were investigated by the Fire Protection Research Foundation, which commissioned numerical analyses and full scale fire tests to gather detailed insights of ceiling slope effects on sprinkler performance.
