Design a rectangular channel contraction from width b1

Reference no: EM13545540

Design a rectangular channel contraction from width b1 (upstream) to width b2 (downstream). Assume uniform flow approaches the contraction (i.e. normal depth approaching the channel contraction).

Given:

Flow rate = Q = 50,000 cfs

Upstream width = b1 = 100 ft

Downstream width = b2 = 75 ft

Manning’s roughness coefficient = n = 0.012

Invert slope = S0 = 0.005
