What is a sprinkler's "K-factor The K-factor is the nozzles's / sprinkler's constant at a given volume flow rate and is generally calculated with a formula: K = Q / √ p K = sprinkler's / nozzle's constant
Q = volume flow rate (l/min)
p = pressure at the sprinkler / nozzle (bar) examples: K-factor 57 = 171 l/min / √ 10 bar
K-factor 80 = 240 l/min / √ 9 bar
K-factor 115 = 345 l/min / √ 9 bar Generally the thread (DN) is associated with a K-factor. 3/8″ DN 10 K-factor 57

What is the k factor in a sprinkler head?
The k factor in a sprinkler head is a coefficient that indicates the flow rate of water through the sprinkler at a given pressure. It is used in hydraulic calculations to determine the amount of water that will be discharged from the sprinkler. A higher k factor means a greater flow rate, which is essential for effective fire suppression. This value helps engineers and designers size the sprinkler system accurately to meet fire protection requirements.
Have there been any recalls on Rasco fire sprinkler heads?
Rasco 1993 H - K 14.2
How many PSI come out of fire sprinkler heads?
Depends on the available pressure If you have 60 PSI coming into a structure then you will get 60 PSI out of the sprinkler Just look at the "K" factoring for friction losses

What is the flow in gallons per minute of a sprinkler with a K Factor of 5.6 and a flowing pressure of 29 psi?
To calculate the flow in gallons per minute (GPM) of a sprinkler with a K Factor of 5.6 and a flowing pressure of 29 psi, you can use the formula: [ \text{GPM} = K \times \sqrt{P} ] Substituting the values: [ \text{GPM} = 5.6 \times \sqrt{29} \approx 5.6 \times 5.385 = 30.1 ] Thus, the flow is approximately 30.1 GPM.
What is the duration of The K Factor?
The duration of The K Factor is 300.0 seconds.
When was The K Factor created?

When did The K Factor end?
The K Factor ended on 2010-03-20.
B If 5 is a factor of k and k is even then 10 divides k?
YES.If k is even then 2 is a factor of k.If 5 is also a factor of k then 2 x 5 = 10 is another factor of k.NOTE : The product of two or more prime factors of a number produces another factor.
What factor is 310 in?
It is a factor in all numbers of the form 310*k where k is an integer.
How do you factor k squared 5k?
k(k + 5)
