What would be effects of applying foam solution at a lower gpm than that listed in the NFPA Standard 11 and relevant manufacturer's design criteria? A scenario is where the existing fire pump is of smaller capacity than what protection of the hazard requires.
eg. recommended design value is 1,000gpm but it is applied at 500gpm for that particular hazard?
Assume the discharge time is increased to allow for the design foam solution volume to be discharged.
