Question:
Design of fluid control circuits, it is desired to control a reactor via continuous analysis of a side stream. Calculate the maximum frequency of concentration changes that can be detected as a function of the volumetric withdrawal rate, if the stream is drawn through a 10 cm length of tubing with an internal diameter of 0.5 mm. Suggestion: Use as a criterion that the standard deviation of a pulse duration be no more than 5% of the cycle time t0 = 2π/w, where to is the frequency it is desired to detect.
