Example 1 Determine, using Hardy-Cross, the flow rate in all the pipes. Do as many iterations as necessary to reach a converged solution. The solution is final solution is given so you may check your work (you will still need to provide a full solution showing all iterations) [Hint it is much easier if you treat BC and CD as one pipe BD, also with the large flow rate entering at point B a good starting point would be to assume flow in AB is-ve. So start your flow B assumptions from point B assuming a small flow in AB with the remainder equally split between BD and BE] Pipeline k Values (s'm') AB - 5000 BC -2500 CD = 2500 DE 5000 AE 5000 BE = 10000 0.045 m/s 0.020 m/s А Solution (note -ve sign denotes direction) Error on flow rates below has a maximum of 2% Pipe a(m/s) AB -0.00422 AE -0.02422 BE 0.01756 BD 0.02322 DE 0.00822 0.05m/s
