Question:

Why does a fireperson sometimes struggle when holding the pipe issuing water? [Pg. No. 110]

Answer: Verified

A fireperson sometimes struggles while holding the pipe issuing water because water comes out with high speed and exerts a backward reaction force on the pipe. Due to this force, the pipe pushes the fireperson backward, making it difficult to hold steadily.
