The Froude number for an open channel flow of velocity U and a depth of h was defined in Chapter 5 as

(a) Calculate the value of the Froude number for a 1-m-deep channel in which the water is flowing at an average speed of 0.5 m/s.
(b) The channel shape was tested in a 1/10-scale model. What is the desirable average velocity in order to keep the same Froude number (and not change the surface-wave behavior)?
