Question 8
Two reservoirs are connected by a pipe whose total length is 360m.From the upper reservoir the pipe is 300mm in diameterfor a length of 150m and the remaining 210m is 450mm in diameter.The difference in water levels between the two reservoirs are 8m.Take f=0.006 for the smaller pipe and f=0.005 for the larger pipe.If all the changes in pipe sections are sharp and sudden, calculate the flow rate which can be delivered.
