Fluid Mechanics Question

nickenrite

If anyone could give any help with this problem it would be much appreciated.

At A, a pipe has a bore(internal diameter) of 100mm and at B it is 150mm. The pressure head at A and B are 21m and 15m water coloumn respectively. There is no pump between A and B while the distance between A and B is 9m measured vertically. the loss of head due to friction between A and B is 2m water coloumn. Determine:

i) The volumetric flow rate through the system
ii) The power dissipated due to friction.

Thanks
