Question

In flowing from section (1) to section (2) along an open channel, the water depth decreases by a factor of two and the Froude number changes from a subcritical value of 0.4 to a supercritical value of 2.5. Determine the channel width at (2) if it is 13 ft wide at (1).

Answer 1

channel width = 2.621 ft

Step-by-step explanation:

Given data :

Decreasing Factor = 2

subcritical value = 0.4

super critical value = 2.5

width = 13 ft
