Question

Time Left 0:07:05 Hans bnat Attempt Water level remains the same The water level decreases Question 9 (1 point) In the first part of the experiment, uniform flow was developed in the open channel. Which of the following is true for uniform flow: the total energy remains constant along the channel the line representing the total energy is parallel to the bed of the channel the specific energy decreases along the channel O the total energy line either rises or falls along the channel depending on the state of the flow Question 10 (1 point) 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: Cannot say based on given information less than 0.009? O greater than 0.009? same as 0.009 Page 2 of 2 Submit Qui 5 of 10 questions saved

Answer 1

solution @ A The total energy remains constant along the channel. Reason: is constant for The specific energy a uniform flow can either decreases increase in a varied flow. marino uniform flow hreater than 0.007. Reason: - for lined canal in concrete manni manning 'n' is always greater than 0.00g because concrete is smooth surface.
