A water pipe at the top of a hill has a cross sectional area of 0.052 m2 and carries a flow rate of 0.75 m3/s. The pressure in this pipe is 1.8 x 105 N/m2. The pipe goes down a 20 m hill where the diameter is reduced to 0.030 m2.
A. What is the velocity of the water in the large pipe at the top of the hill?
B. What is the velocity of the water in the small pipe at the bottom?
C. What is the pressure in the small pipe at the bottom?
