Find the speed at which water travels in a pipe if the height is

Question

a. 5cm. b. 8cm. c. 18 cm.
[Use the formula v^2=1960(h+10).]

Answer 1

I do no recognize where the +10 term comes from. What height h are they talking about? It probably has something to do with the vertical height of the water surface above the outlet.

Evidently they want you to substitute 5 cm for h in part (a) and solve for v. It will be in cm per second.

Then do it again with h = 8 cm and h = 18 cm.
