a.) 2.0 inches; 3.0 inches

b.) 2.0 inches; 4.0 inches

c.) 2.5 inches; 3.5 inches

d.) 2.5 inches; 4.5 inches

The typical diameters of nozzles used in hydrants in water systems are 2.5 inches and 4.5 inches.

Hydrants with two nozzles of 2.5 inches in diameter and one nozzle of 4.5 inches in diameter are commonly used in water systems. These hydrants play a crucial role for fire departments and emergency responders in accessing water during fire emergencies.

The two smaller nozzles, with a diameter of 2.5 inches, are typically used for hose connections and allow for a controlled flow of water. On the other hand, the larger nozzle, with a diameter of 4.5 inches, is used for higher volume water discharge and firefighting purposes.

Hydrants are strategically located throughout communities to ensure quick access to water in case of fires. They are connected to underground pipe networks that supply water to homes and businesses as well.

Regular maintenance and testing of hydrants are essential to ensure their proper functioning when needed. Fire departments often conduct inspections and maintenance to keep hydrants in good working condition.
