Problem 1 Solution
Question: Sketch the hydraulic head gradient along the length of the cylinders below.
Solution:
- Flow is from right to left. Therefore, the head decreases to the left.
- Gradient must be steeper in Section A than in Section B, because the cross-sectional area of Section A is less than in Section B, while both sections have the same K.
- Gradient in Section C is steeper than in Section A, because K in Section C is less than in Section A, while both sections have the same area.
- Gradient in Section C is the steepest, because it has the lowest K while also having a small cross-sectional area.
