Question: A 6 cm diameter pipe is used to drain a water reservoir. The elevation difference between the reservoir water surface and the pipe exit

A 6 cm diameter pipe is used to drain a water reservoir.

A 6 cm diameter pipe is used to drain a water reservoir. The elevation difference between the reservoir water surface and the pipe exit is 50 m. If the pipe is 400 m in length and f is 0.028, determine the time it will take to reach 25% of the steady state velocity. [20] A 6 cm diameter pipe is used to drain a water reservoir.
