Determine a, b numbers using your student ID number. An example: Student Number= 216 CE2504L 216 CE2ab4L→ a=5, b=0. What is your a= ,b= ? Question: A sewer pipe placed on the bottom of the rectangular channel with Manning roughness coefficient n-0.0167 s/m¹/3 as given in the figure. The energy of the incoming subcritical flow is not sufficient to overpass this submerged pipe. i) Draw the detailed variation of the flow depth around the pipe section on the figure below when the flow occurs. Ŏ1e=1 E E E₁ En ii) When the flow occurs, the flow depth right above the pipe is 2+b/50 meters. Using this value: Calculate the minimum specific energy Emin Calculate the discharge in the channel and the critical slope le, of the channel. If the uniform flow depth is yo= 3.2+a/20 m, calculate the specific energy E and determine its regime. What is the alternative depth for this specific energy level of Eg? Qo, yo y=2+b/50 meters K+ 8-5m Yo
