Two reservoirs A and B have a difference in level of 9

Two reservoirs A and B have a difference in level of 9 m and are connected by a pipeline 200 mm in diameter over the first part AC, which is 15 m long, and then 250 mm diameter for CB, the remaining 45 m length. The entrance to and exit from the pipes are sharp and the change of section at C is sudden. The friction coefficient fis 0.01 for both pipes. (a) List the losses of head (energy per unit weight of flowing liquid) which occur, giving an expression for each.
