A high flow velocity will accelerate the disk and slam the valve shut. This phenomenon is known as check valve “slam” and is a common cause of water hammer. If there is a possibility of severe ...

The results revealed that the water-flow velocity increased with increasing swimming speed during the underwater dolphin-kick lower-limb action, generating a strong vortex during the kicking action.

Cross-flow turbines, also known as vertical ... based on the chord length and free stream velocity, was 31,000. The temperature of the water was maintained at 15 ∘ C. The turbine consisted ...

The dark water is not from pollution, but rather from the tannic acid that leaches out of the abundance of dried leaves that fall into the swamps and tributaries that flow into the river.
