1) You have used a Manning n value of 0.009 for the open channel in the lab. You would expect Manning n for a concrete lined channel to be: a. less than 0.009? b. same as 0.009 C. greater than 0.009? d. Cannot say based on given information 2) In the first part of the experiment, uniform flow was developed in the open channel. Which of the following is true for uniform flow: a. the total energy remains constant along the channel b. the total energy line either rises or falls along the channel depending on the state of the flow c. the specific energy decreases along the channel d. the line representing the total energy is parallel to the bed of the channel 3) What happens to the water level in the channel when a hump is placed in the channel when the flow is subcritical? a. The water level increases b. The water level decreases
