5. A wet-pipe sprinkler system uses sprinkler heads that have a K-factor of 8.2. The pressure at the heads is 18 psi. During a fire 5 heads opened and discharged water for 7 minutes. Calculate how much water was discharged using the formula Q = (K)(?P) where Q = the water flow in gallons per minute from one head K = the K-factor P = the pressure in psi at one head
