Question 1. Two tanks are connected together in the following unusual wa : W1. h1 h2 W3- Develop a model for this system that can o' wea to find h, ha, wa and * vs as functions of time for any given variations in input . Notes The den ity of the incoming liquid p in constant The cross sectional areas of the two tanks are A, and A,. w, is positive for flow from Sank ! to Tank .. The two valves a e linear with . esistances Re and Rs. Question 2 A stream contains a waste chemical, W, with a concentration of 1 mol/liter. To meet Environmental Protection Agency and State standards at least 90% of the chemical must be removed b' reaction. The chemical decomposes by a second order reaction with a rate constant .= 1.5 liter/(mol hr) The stream flow rate is lou liters/hour and two available reactors (400 and 2000 liters) have been placed in series (the smaller reactor is placed before the larger one). a. write the modeling equations for the concentration of the waste chemical. Assume constant volume and constant density. Let: Lwe-concentration in reactor 1, mol/liter Cw:- concentration in reactor 2, mol/liter F=volumetric flow rate liter/hr Vi-liquid volume in reactor 1, liters Va-liquid volume in reactor z, liters
