a. Write the most general form of the mass balance equation for ANY control volume with multiple mass flow rate inlets and outlets. b. Consider the specific case of a rectangular tank (oriented vertically as shown in the accompanying figure) that is being filled with the same liquid from two different pipes. If the cross-sectional areas and average velocities for the two pipes are designated as AA,AB,VA, and VB respectively, simplify the equation from part a) to get the appropriate expression for the rate at which the liquid level (h) in the tank is changing with respect to time. c. Calculate the time (min) it takes to raise the liquid level in the tank from 1m to 3m given the following details: s=1.5mAA=0.012m2AB=0.008m2VA=0.3m/sVB=0.6m/s
