An engineer is hired to design a swimming pool 15m long by 6m wide by 2m deep. For water supply, he decideds to lay 600m of 5cm pipe with f=0.020 from a nearby main to the pool. The pipe will discharge freely into the pool during the entire filling process. The average pressure at the water main is 550kpa and the difference in elevation between the two ends of the pipe is 10m, with the discharge end higher than the intake end. Assuming that 10% of the loss in the pipeline are due to transitions, fittings and valves, how long would it take to fill the swimming pool?
