What will happen if the pump's net discharge pressure is less than required?

When a pump's net discharge pressure falls below the required level, it can lead to an ineffective fire stream. Firefighting operations heavily rely on having the right pressure to achieve proper water flow and reach the fire effectively. Insufficient pressure can result in a weak or erratic stream that lacks the necessary reach and force to extinguish a fire or protect exposures. A fire stream that is too weak can lead to inadequate cooling, the inability to penetrate the fire, and an overall reduction in firefighting effectiveness. Therefore, maintaining the correct net discharge pressure is crucial for ensuring that the fire stream meets operational needs and can effectively combat flames.
