hello fire experts what NFPA13 requires minimum and maximum pressure for hose streame inside and the hydrant outside
NFPA 13 does not pressure requirements for hose stream allowances. When performing hydraulic calculations, the flow is added to the system but no minimum or maximum pressure is calculated. If hose streams must be calculated separate from the sprinklers, then you should consult NFPA 14 for design requirements including maximum and minimum pressure.
