Two large tanks are connected by two pipes of different size in
parallel. Water temperature is 20°C.
The surface water elevation in the upstream reservoir (Reservoir
I) is 175m. The length of each pipe is 1250 m, and other properties
are specified in the following:
Pipe A: diameter 0.5m, and frictional factor 0.025;
Pipe B: diameter 0.25m, the frictional factor is not given, but
relative roughness is 0.006 under the flow condition
observed.
Flow velocity in Pipe A is 2m/s....
