Question:

Water at \(18^{\circ} \mathrm{C}\) flows at a depth of \(24 \mathrm{~cm}\) with an average velocity of \(4.3 \mathrm{~m} / \mathrm{s}\) in a wide rectangular channel. Determine

(a) the Froude number,

(b) the critical depth, and

(c) whether the flow is subcritical or supercritical. What would your response be if the flow depth were \(6 \mathrm{~cm}\) ?
