As a graduate you are required to design a 15.3 km water pipeline to convey a discharge of Q=0.4-x/3000 cumecs between two large reservoirs in a large regional city, using the Moody diagram and the Darcy-Weisbach friction equation. The pipe material will be UPVC and internal diameters available from the preferred supplier are in 50 mm increments starting from 50 mm ID. In this pipeline there will be five 90° elbows, a fully open swing check valve, three gate valves that are fully open, and two 45° bends, with the pipeline fitting flush with the reservoir walls. If the elevation difference between the water surfaces is y = 25 + x/11 metres, what minimum pipeline diameter will be required to convey the design discharge? Once your design is complete, determine the actual discharge. The value of x equals 23.
If the queue clears exactly at the end of the effective green D/D/1 queuing applies, determine the total vehicle delay in the cycle (in veh-sec) .
Assume that during the analyze stage an obvious solution is discovered. Should that solution be immediately implemented and the remaining steps of DMAIC abandoned?
The brush is immersed in the first volume and agitated until equilibrium is established, removed and the exercise is repeated with the second volume. Assume that the solvent remaining in the brush after it is removed from the first batch is insign..
