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.

Expert Solution

Step 1: Given data

Given -

At the downstream cross-section (subscript 2):

Depth, $d subscript 2 equals 1.4$
Specific discharge, $q subscript 2 equals 10.0 space bevelled m squared over s$
Height of the energy grade line, $E subscript 2 equals 4.0 space m$

$d subscript 1 equals ? V subscript 1 equals ? q subscript 1 equals ? V subscript 2 equals ?$
