A large vented tank containing water at 20 C has a pipe discharging to the atmosphere horizontally from the bottom. The pipe is 2.3 cm in diameter, has a surface roughness of 0.046mm, and is 40m long. The velocity in the pipe is 3.5 m/s. The flow in the pipe is turbulent. Neglecting minor losses, what is the water level in 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 maximum water height where the flow could be assumed laminar?

2.56 cm

4.1 m

1.1 m

6.3 m

You are studying the laminar flow of water in a pipe at 20˚C. The pipe is 2 cm in diameter, and the pressure gradient driving the flow is 0.8 Pa/m. Find the x-sectional average velocity (Poiseuille’s Law) and the maximum velocity achieved at the centerline of the pipe (use the equation for Umax presented in the alternative derivation of Poiseuille’s Law). How many times greater is the maximum velocity compared to the average velocity? Is this ū/umax ratio constant or...
