Question:

Investigate the possibility of frictional effects in the venturi flume of Prob. 10.113, part
(a) For which the frictionless solution is Q = 9.88 m3/s. Let the contraction be 3 m long and the measurements of y1 and y2 be at positions 3 m upstream and 3 m downstream of the contraction, respectively. Use the modified gradually varied theory of Prob. 10.115, with n = 0.018 to estimate the flow rate.
