Derive the response equation for change in level if area of tank is 10m2, normal level is 9m when inflow is 6m3/s and the inflow is increased to 7.5m3/s. (Assume laminar flow) Flot=h/R Question Four Consider a CSTR with a second order irreversible reaction 2AB. The modeling equations are vCAOvCAkCA2V=dtVdCA The following parameters and steady state input values characterized this system; rA= kCA2(mol/Lmin),k=2(mol/L)1m1,v=5L/min,CA=0.2mol/L,CAO=1.0mol/L, V=501 a) Obtain the transfer function relating CA to CAO i.e. G(S)=CAO(S)CA(S) b) For a step increase of 0.2 gmol/litre in CA0, obtain the corresponding response of CA(t)
