Gravity flow
principle
The movement of a liquid under the force of gravity.
Principles and materials it uses
- Universal gravitation — uses. It flows downhill under gravity.
Where it is used
- Aqueduct — is used in. Water flows down a gradient without pumps.
- Water clock (clepsydra) — is used in. Water flows out at a constant rate under gravity.
- Water wheel — is used in. Falling or flowing water turns the wheel.
- Flush toilet — is used in. Flushing by gravity.
- Sewerage — is used in. Waste water flows down a gradient.
- Hourglass — is used in. Sand pours through under gravity.
- Canal lock — is used in. The chamber fills and empties by gravity.
- Qanat — is used in. Water flows by gravity.
- IV drip — is used in. The solution flows under gravity.
- Gutter — is used in. Drainage.
- Water filter — is used in. Water seeps through by gravity.
- Water turbine — is used in. It is turned by falling water.
