Study Notes
Navigation Locks
- The purpose of extending side culverts through a landing wall to form cross culverts at equal distances is to facilitate the filling or emptying of a lock chamber.
Time Variables
- 't1' represents the time taken to fill or empty a lock chamber.
Lock Gates
- Sluice gates installed in lock gates are used in addition to another feeding system to control the flow of water into or out of the lock chamber.
Water Conservation
- Water conserving basins are used to conserve water in the context of lock chambers.
Lock Chamber Dimensions
- The minimum depth of water in the lock chamber is not specified in the given data.
Navigation Lock Function
- The function of Navigation Locks is to raise or lower vessels between two levels of water.
Feeding Systems
- One type of Navigation Locks feeding system NOT mentioned in the text is not specified.
Vessel Dimensions
- Common vessel dimensions mentioned in the text are not specified.
Side Culvert Feeding
- Side Culvert feeding exists in the system where water is drawn from the upper pool and fed into the lock chamber.
Regulator Function
- The purpose of a Regulator in relation to a Navigation Lock is to control the flow of water into or out of the lock chamber.
Structural Calculations
- The formula e = tw/2 – x is used to calculate the thickness of the lock chamber wall.
- The formula X = Mo/tw is used to calculate the bending stress in the lock chamber wall.
- The formula f = - N/tw(1 ± 6e/tw) is used to calculate the shear stress in the lock chamber wall.
