NOTES
Refer to local procedures for pump testing procedures and practices.
Use a fog nozzle ONLY in conjunction with flow meters, Use ONLY a nozzle rated for
the required flows.
Conduct testing between 60 and 70 psi for most accurate results.
For pitot gauge accuracy, the pressures should be between 30 and 120 psi. Table 10 provides
nozzle flow (in gpm) and pressures (in psi) for various nozzle sizes (in inches).
