Water flows along a 250mm diameter water main, which has a Darcy friction factor value of 0.026, at a flow rate Q of 24 litres/sec. The pipe is 640m long, has a level of 280m Above Ordinance Datum (AOD) at the start and 276m AOD at the end. If the pressure at the start is 6 bar determine the pressure at the end. Explain why the pressure has increased/varied over the pipe length.
