As shown a sedimentation pond with an outlet pipe and a riser structure. The pipe is new concrete pipe with roughness coefficient of 0.011 and slope of 2%. The length is 50 m and discharges freely to a channel. The riser rectangular concrete box of 2 m by 1.5 m. The maximum water level is 100 m. The top of riser level is 98 m. The elevation of the outlet pipe invert at inlet and the bottom of pond is elevation 96.5. (3 p) A Given that the riser pipe behave as an orifice with C = 0.62, Calculate the discharge through the outlet in m3/s. (3 p) B Given that the riser pipe behave as a rectangular weir, find Q if the pipe discharge freely. (2 p) C Given that the riser pipe behave as a sharp crested weir with nappe, find the value of C for the weir. (3 p) D If pipe is flowing full (non-pressurized), determine the discharge in m3/s. (3 points) E lf pipe is flowing at 40% of its depth, find the partial velocity and partial flow rate in the pipe. * HW Ele100 Top of riser fle 98 m rutie, Sin and
