Determine K Factor Sprinkler Head. What is a sprinklers K-factor The K-factor is the nozzless sprinklers constant at a given volume flow rate and is generally calculated with a formula. Lets take an example we wish to find the flow from a fire sprinkler head and we know the K-factor is 608 and the pressure to the head is 068 Bar then the flow from the sprinkler will be 5014 Lmin this is illustrated below. The k - factor is dependent upon the orifice diameter of the sprinkler - a low k - factor such as K2. The k-factor for different sprinkler heads may range from k 56 standard ½ orifice to k140 for ESFR sprinklers.
