A firehose rodeo contestant is riding a hose that sprays water vertically downward from a 1 inch diameter nozzle attached to a 5 inch diameter hose. The contestant, the water in the hose, and the hose together weigh 155 lbf. What flowrate of water is needed to keep the contestant from falling to the ground? Report your answer in ft s1, to the nearest 0.1 ft³ s-1.

Question
A firehose rodeo contestant is riding a hose that sprays water vertically downward
from a 1 inch diameter nozzle attached to a 5 inch diameter hose. The contestant,
the water in the hose, and the hose together weigh 155 lbf. What flowrate of water
is needed to keep the contestant from falling to the ground?
Report your answer in ft3 s1, to the nearest 0.1 ft³ s-1.
Assume
• Pw =1.94 slug ft3
• There is no tension from the hose, so its full weight must be supported by the
water stream.
• The pressure in the hose is 219 Ibf in 2
• The flow is not inviscid
slug
p =1.94
