The Nelson Mandela Bay Municipality (NMBM) drawing number P093 shows a trapezoidal channel with construction detail. Study all the given information and answer the following: a) If the water level in the channel reaches the top edges of the concrete channel (completely full), calculate the discharge if the longitudinal slope is 2,4%. b) State the Froude number and type of flow for (a). c) Test the channel for buoyancy. d) Determine the safety factor (FOS) for this channel against buoyancy. 1:20 300 BITUMEN PRIME 0.71/ OR 20 MIOPRON POLYETHYLENE SHEETING 12800 LIN *200mm / DATE OF LAST REVISION NOTES: 1.
