1. Water enters one end of a perforated pipe 0.2 m in diameter with a velocity of 6 m/s. The discharge through the pipe wall is approximated by a linear profile. If the flow is steady, find the discharge velocity.
2. The velocities in a circular duct of 20-in. diameter were measured as follows:
Find
(a) the average velocity;
(b) the flow rate in cubic feet per second.
