WebThis means that a 1000mAh battery would provide 1000mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C would provide 500mA for two hours. At 2C, the 1000mAh battery would deliver 2000mA for 30 minutes. 1C is often referred to as a one-hour discharge; a 0.5C would be a two-hour, and a 0.1C a 10-hour discharge. dfa the creameryWebWhere: Q = discharge in m 3 /sec or ft 3 /sec A = cross-sectional area of flow in m 2 or ft 2 v = mean velocity of flow in m/sec or ft/sec ρ = mass density of fluid in kg/m 3 or slugs/ft … dfat human rightsWebSTREAM DISCHARGE MEASUREMENT (STREAM GAUGING) The discharge Q from creeks, small streams and rivers can be determined by a number of methods, four of … church usher board clip artWebThe discharge of a river (or stream) is the volume of water that streams past a point in the river’s course every second.
