Water flows from the reservoir on the left to the reservoir on the right at a rate of Q. Q = 4.2 m³/s The formula for the head losses in the pipes is hL = 0.02(L/D)(V²/2g). Assume the head-loss formula can be used for the smaller pipe as well as for the larger pipe. Assume a = 1.0 at all locations and v = 1.06 x 106 m²/s. Take the minor loss coefficient of entrance, contraction and outlet as 0.5, 0.25 and 1.0, respectively. (i) What elevation in the left reservoir is required to produce this flow?
