A laboratory hydro test installation has a vertical drop of 10 feet. The system produces a total of 150W. You are testing water and ethanol to determine which liquid will have a higher efficiency. When you test water, you are able to achieve 1.9 gal/s of flow, while when you test ethanol, you are able to achieve 2.3 gal/s of flow. Which liquid has the higher efficiency
