Question
![Consider a steady state flow situation illustrated below. How high will the water level h,
stand in the pipe (D = 0.1 [m]) if the flow rate of water at steady state is F = 0.0005 [m³/s].
The pipe is partially (L = 0.5 [m]) filled with spherical marbles of dp=2.5 [mm] in diameter.
Calculate the level 'h' of water in the pipe at steady state condition.

No Hints! You are experienced modelers now!.....OK, OK - Think about these questions:
1. Where will (between which two points) I apply the MEB?
2. What is the driving force for flow?
3. What is the source of friction resisting the flow?
