7. A 20hp suction pump operating at 70% efficiency draws water from a suction line whose diameter is 200mm and discharges into air thru a line whose diameter is 150mm. The velocity in the 150mm line is 3.6m/s. If the pressure at point A in the suction line is 34kPa below the atmosphere, where A is 1.8 m below B on the 150mm line, determine the maximum elevation above B to which water can be raised assuming a headloss due to friction.
