8.59 Two tanks A and B, of constant cross-sectional area of 10 m² and 2.5 m², respectively, are connected by a 5 cm pipe, 100 m long, with f = 0.03. If the initial difference of water levels is 3 m, how long will it take for 2.5 m³ of water to flow from A to B? Considering entry and exit losses, it can be grossly assumed that the flow velocity, in m/s, through the pipe is 1.75√h, where his in m, taking g = 10 m/sec², also, may take area of pipe as 2 x 10-3 m².
