Problem 8.20

At time t = 0 the level of water in tank A shown in Fig P8.20 is 2 ft above that in tank B. Plot the elevation of the water in tank A as a function of time until the free surfaces in both tanks are at the same elevation. Assume quasi-steady conditions— that is, the steady pipe flow equations are assumed valid at any time, even though the flowrate does change (slowly) in time. Neglect minor losses. Note:Verify and use the fact that the flow is laminar
