This is around 1 ⁄ 5 (20%) of what is needed to power a standard upright bicycle without aerodynamic cladding at same speed, and 1 ⁄ 50 (2%) of that which is consumed by an average fossil fuel or electric car (the velomobile efficiency corresponds to 4700 miles per US gallon, 2000 km/L, or 0.05 L/100 km).

The Catskill Aqueduct carries water to New York City over a distance of 120 miles (190 km), but is dwarfed by aqueducts in the far west of the country, most notably the 242-mile (389-km) Colorado River Aqueduct, which supplies the Los Angeles area with water from the Colorado River nearly 250 miles to the east and the 701.5-mile (1,129.0 km ...
The nearly 12,000 miles (19,000 km) of U.S. inland and intracoastal waterways maintained by the Army Corps of Engineers includes 191 commercially active lock sites with 237 lock chambers. Some locks have more than one chamber, often of different dimensions.
Gasoline and diesel fuel are sold by the U.S. gallon, and fuel economy is rated in miles per gallon (MPG). In most other countries, using the metric system, fuel consumption is measured in liters per 100 kilometers or kilometers per liter. The European Union official standard is liters per 100 km. [109]
A car that gets 34 miles per gallon is more fuel efficient than one that gets 32, but it's hardly. Skip to main content. 24/7 Help. For premium support please call: ...
In the United States, it is computed per 100 million miles traveled, while internationally it is computed in 100 million or 1 billion kilometers traveled. According to the Minnesota Department of Public Safety, Office of Traffic Safety Volume of traffic, or vehicle miles traveled (VMT), is a predictor of crash incidence.
This article lists rivers by their average discharge measured in descending order of their water flow rate. Here, only those rivers whose discharge is more than 2,000 m 3 /s (71,000 cu ft/s) are shown. It can be thought of as a list of the biggest rivers on Earth, measured by a specific metric.
The distribution system is made up of an extensive grid of water mains stretching approximately 6,800 miles (10,900 km). As of 2015, it costs the city $140 million to maintain these mains. [15] There are 965 water sampling stations in New York City. The water-sampling system has been in use since 1997.
