Question 53Safety & Environmental - 1st Asst/Chief
70% to passAs a general rule of thumb, with no adverse wind conditions, approximately how far could a straight stream of water reach from a fire hose having a nozzle pressure of 100 psi?
A50 feet
B100 feet
C150 feet
D200 feet
AI Explanation
The correct answer is B) 100 feet. The typical range for a fire hose with a nozzle pressure of 100 psi and no adverse wind conditions is approximately 100 feet. This is based on the general principle that water pressure and flow rate are the primary factors determining the maximum effective reach of a fire stream. At 100 psi, the water can be projected a distance of around 100 feet before gravity and air resistance cause the stream to dissipate. The other options are incorrect because 50 feet (A) would be too short for a 100 psi nozzle pressure, while 150 feet (C) and 200 feet (D) would be beyond the typical effective range without specialized equipment or conditions.
