In a time-varying pressure measurement, the maximum frequency of interest is 100 Hz, but there are frequencies in the signal with significant energy up to 1000 Hz. A first-order Butterworth filter is to be constructed to filter out the higher frequencies. If the ND convert�r has 8 bits and is bipolar, determine the minimum sampling rate for an attached data-acquisition system.

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?
