01(a) There are two reservoirs, A and B, with the water surface elevation in A 10 m higher than that in B. These are connected through two pipes in series with pipe 1 starting from A and pipe 2 ending in B. Lengths of both the pipes are 100 m, diameter of pipe 1 is 30 cm and diameter of pipe 2 is 25 cm. At the junction of these pipes, water is being withdrawn at the L v² D 2g rate of 0.02 m³/s. Friction loss in the pipes is given by h = f and the Darcy friction, f, entrance and at the junction, for both pipes is 0.02. Neglecting the head losses at the estimate the total water withdrawal from reservoir A.
