What is the range of GPM ratings for a typical 1 3/4" nozzle?

The range of GPM (gallons per minute) ratings for a typical 1 3/4" nozzle is indeed correct when identified as 70-200 GPM. This size of nozzle is commonly used in fire suppression operations due to its versatility and effective flow rate for various firefighting scenarios.

The 1 3/4" nozzle is designed to deliver a substantial amount of water which helps to combat fires efficiently, particularly in structural fire situations. A flow rate of 70-200 GPM allows firefighters to adjust the water output based on the conditions they face, making it an essential tool for both defensive and offensive firefighting strategies.

The upper limit of this range, at 200 GPM, reflects the capability of modern firefighting nozzles to produce higher flow rates to tackle larger fires, while the lower limit ensures adequate water supply for smaller or more controlled situations. This flexibility allows firefighters to effectively manage various types of incidents.

In summary, the versatility of the nozzle and its adaptive flow rates make the range of 70-200 GPM appropriate for a 1 3/4" nozzle in typical firefighting operations.
