Four lawn sprinkler heads are fed by a 1.9 cm diameter pipe. The
water comes out of the heads at an angle of 35° to the horizontal
and covers a radius of 7.8 m.
(a) What is the velocity of the water coming out of each
sprinkler head? (Assume zero air resistance.)
m/s
(b) If the output diameter of each head is 3.0 mm, how many liters
of water do the four heads deliver per second?
L/s
(c) How fast is the water flowing inside the 1.9 cm diameter
pipe?
m/s
