A rotary encoder is connected directly to the spindle of a machine tool to measure its rotational speed. The encoder generates 144 pulses for each revolution of the spindle. In one reading, the encoder generated 267 pulses in a period of 0.25 sec. What was the rotational speed of the spindle in (a) rev/min

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
