That is, the car will be moving ( 6000 * 6.28 * r) / (R1*R2) inches per minute. Since 1 mile = 5280 feet = 63,360 inches, and 1 hour = 60 minutes, then the conversion from inches per minute to miles per hour is ( 60 / 63,360 ). So, if the engine is turning 6000 rev/min then the car must be going (60 / 63,360) * ( ( 6000 * 6.28 * r) / (R1*R2) miles/hour.
Kaieteur Falls is the world's widest single drop waterfall, located on the Potaro River in the Kaieteur National Park, in Essequibo, Guyana.Its location is in the Amazon forest.aieteur Falls is about four times higher than the Niagara Falls, on the border between Canada and the United States, and about twice the height of the Victoria Falls, on the border of Zambia and Zimbabwe in Africa.
Located on the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls form the highest flow rate of any waterfall in the world, with a vertical drop of more than 165 feet (50 m). Horseshoe Falls is the most powerful waterfall in North America, as measured by vertical height and also by flow rate.he larger Horseshoe Falls are about 2,600 feet (790 m) wide, while the American Falls are 1,060 feet (320 m) wide. The distance between the American extremity of the Niagara Falls and the Canadian extremity is 3,409 feet (1,039 m).
