ou’ve sent your assistant out to measure the flow properties of a frictionless rectangular flat channel. Your assistant returns with measurements for the depth (d2 = 1.4 m), the specific discharge (q2 = 10.0 m2/s), and (somehow) the height of the energy grade line at 4.0 meters all at the downstream cross section. They haven’t done a spectacular job leaving you to solve for d1, q1, V1, and V2. There are two potential answers for d1 and V1.

Question

You’ve sent your assistant out to measure the flow properties of a frictionless
rectangular flat channel. Your assistant returns with measurements for the depth (d2 =
1.4 m), the specific discharge (q2 = 10.0 m2/s), and (somehow) the height of the energy
grade line at 4.0 meters all at the downstream cross section. They haven’t done a
spectacular job leaving you to solve for d1, q1, V1, and V2. There are two potential
answers for d1 and V1.
