Two large tanks are connected by a cast iron pipe 50mm in diameter and 50m long. There are eight 60 degree and four 90 degree bends along the length of the pipe. The inlet to and the exit from the pipe are abrupt and the rate of flow of water through the pipe is 6 litres/second. Determine the difference between the supplying and recieving tank.

The following values may be assumed for the loss coefficients k:

abrupt entrance k=0.5 abrupt exit k=1.0

60 degree bend k=0.45 90 degree bend k=1.15

I would appreciate any help anyone can give me. Thanks
