A firehose must be able to shoot water to the top of a building 38.0 m tall when aimed straight up. Water enters this hose at a steady rate of 0.515 m3/s and shoots out of a round nozzle.
(a) What is the maximum diameter this nozzle can have?
1 __________ cm
(b) If the only nozzle available has a diameter twice as great,
what is the highest point the water can reach?
2______________
1)
(a)
Rate of Volume of liquid flowing (V/t) = Area(A) * Velocity(v).
D = 0.155 m = 15.5 cm
2)
If Diameter is doubled the maximum height reached by the water can be calculated using equation of continuity.
h2 = 2.375 m
