    Sprinkler Flow Calculator (K-Factor)

    Can I use pump pressure instead of sprinkler pressure?

    No. Use pressure at the sprinkler outlet after accounting for elevation and friction losses through the piping network. Pump discharge pressure is upstream and can overstate actual sprinkler discharge if losses are not removed.
