6.6 In the level tank shown in the figure, A1=A2=10ft^3, R1=0.1ft/cfm, R2=0.35ft/cfm. In the normal state, q is maintained at 20cfm. Now, at some point t=0, 10ft^3 of water was suddenly injected into the first tank. Find the maximum value of H2(t) and the time at this time. The effluent flows from the first and second tanks are given by q1 = h1/R1 and q2 = h2/R2, respectively.
