GUATEMALA CITY - Torrential rains brought by the first tropical storm of the 2010 season pounded Central America and southern Mexico, triggering deadly landslides. The death toll stood at 15 Sunday but authorities said the number could rise.
Archimedes proved the formula for the area of a circle (A = Ï r 2, where r is the radius of the circle) and showed that the value of Ï lay between 3 + 1/7 (approximately 3.1429) and 3 + 10/71 (approximately 3.1408).
What is A/R? The A/R in a relationship that is obtained when dividing the interior area of the turbine where the inner walls are found, through the turbine housing radio from the center to the tongue as the illustration indicates. A/R values are expressed as .35, .47, .68, .84, 1.00, 1.15, etc. A small A/R indicates a small interior volume in the small turbine and a large A/R indicates a greater volume. At a minimum A/R the motor's response is produced at small revolutions per minute but at high revolutions we will not achieve an adacuate caudal.
