A fire-hose must be able to shoot water to the top of a building 35.0 m tall when aimed straight up. Water enters this hose at a steady rate of 0.500 m³.s¯¹ and shoots out of a round nozzle.

(a) What is the maximum diameter that this nozzle can have?

(b) If the only nozzle available is twice as great, what is the highest point that the water can reach?

2. Relevant equations

flow rate = pir^2 x h/1

3. The attempt at a solution

(a) 0.5 = pi r^2 x 35 / 1

r = 0.067m

(b) 0.5 = pi x 0.134^2 x h/1

h = 8.86m

Can someone please check I am doing this correctly. Thanks!
