An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel). The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.
While some causes are obvious, such as hurricanes and snow melt, many are not. Heavy Rains: Cresting rivers, backed-up storm drains, or saturated ground can cause significant floods. Heavy rains can contribute to flash floods, which are the number one weather-related killer in the United States. A flash flood is a rapid flooding of low-lying areas in less than six hours. Heavy rains also increase the chance of mudflows, rivers of liquid, and flowing mud.
Food and Water Safety. When In Doubt, Throw It Out. Illnesses caused by food borne bacteria can be among the greatest problems caused by a hurricane or flood. Both loss of power and flooding pose a threat to your food supplies. In high water and flooding, food, water and utensils can be contaminated with bacteria, sewage and/or chemical spillage.
