Water flows from Tank 1 to Tank 2 through 300 feet of 4 inch cast iron pipe at a flowrate of 0.5 ft3/sec, as indicated in the sketch below. The system includes a slightly rounded entrance at location 1, two regular threaded 45 degree bends at location 2 and 3, a fully open ball valve at location 4 and a sharp-edged exit at location 5. Information on the loss coefficients is below.
Loss coefeicients:
Fully open globe valve: 10.0
45 degree bend 0.2
90 degree bend 0.4
Entrance (sharp edged) 0.5
entrance rounded 0.05
exit sharp edged 1.0
