A large vented tank containing water at 20 C has a pipedischarging to the atmosphere horizontally from the bottom. Thepipe is 2.3 cm in diameter, has a surface roughness of 0.046mm, andis 40m long. The velocity in the pipe is 3.5 m/s. The flow in thepipe is turbulent. Neglecting minor losses, what is the water levelin the tank above the centerline of the outlet pipe?
2.1 m
28.3 m
13.6 m
39.2 m
With the same setup (except water velocity), what is the maximumwater height where the flow could be assumed laminar?
2.56 cm
4.1 m
1.1 m
6.3 m
