Figure 1 shows a pump P pumping 72 itres/sec of water from a tank. 

ii. what will be the pressures at points L and M when the pump delivers 12Kw of power to the flow. Assume the losses in the system to be negligible. 

ii. what will be the pressure at M when the loss in the inlet up to the pump is negligible and between the pump and the point M, a loss equal to 1.8 times the velocity head at B takes place.
