Question 903 Deck Safety

70% to pass

Approximately how far could a straight stream of water reach if the fire hose pressure is reduced to 60 PSI?

A 50 feet
B 150 feet
C 100 feet
D 200 feet
AI Explanation

The correct answer is A) 50 feet. At a reduced fire hose pressure of 60 PSI, the maximum reach of a straight stream of water would be approximately 50 feet. This is based on the general principle that water stream reach is directly proportional to the square root of the water pressure. Reducing the pressure from a typical 100 PSI to 60 PSI results in a reduction in reach by a factor of the square root of (60/100), or about 0.77, which corresponds to a maximum reach of around 50 feet. The other options are incorrect because 150 feet (B) and 200 feet (D) would require significantly higher water pressures, while 100 feet (C) is an overestimate for a 60 PSI pressure scenario.
