You are given a channel that is rectangular with the following values: n = 0.015, b = 13 ft and Q = 1,042 cfs. Calculate the height of the step z in feet that will cause the flow to be critical when the depth upstream of the step is 6 feet. Please enter your answer as a numeric value only (excluding units) rounded to the nearest hundreds place. Z =

The rectangular channel is 2 m wide, and the depth of the water is y₁ = 1.6 m as it flows with an average velocity of V = 0.6 m/s. (Figure 1) Figure < 1 of 1 Part C Determine the required height of the bump so that the flow can change to rapid flow after it passes over the bump.

do not round off everything plsss

I need help with this question. My three previous answers were 0.139, -0.21, and 0.20.The question keeps saying to check units, but am at a loss of how to solve this.
