Hydraulic ram, an Uncommon card

The card carries these facts from its Wikipedia article.

• It takes in water at one "hydraulic head" and flow rate, and outputs water at a higher hydraulic head and lower flow rate.
• The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started.
• The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source.
