Homework Statement
Four lawn sprinkler heads are fed by a 1.9cm diameter pip.e The water comes out of the heads at angle of 35 degrees to the horizontal and covers a radius of 8m.
a) What is the velocity of the water coming out of each sprinkler head?
b) If the output diameter of each head is 3.0mm, how many liters of water do the four heads deliver per second?
Homework Equations
Continuity: A1*v1 = A2*v2
The Attempt at a Solution
For (a), I see the water covers a radius of 8m, so an area of 64pi meters. It must do this in a horizontal direction, so the speed is only in the X direction. I don't really know how to find out velocity though, because we don't know any other velocity.
For (b) I assume once you just multiply the area by the velocity found in (a)
