Consider the water pump shown in fig, Determine the power that the pump supplies to the water if the velocity of the water is at A is V= 2 m/s and the pressures at A and B are 175kPa and 350 kPa, respectively. Neglect friction losses.
A centrifugal pump is discharging 900 gpm and which operates at 1800 rpm against a head of 120 ft and maximum efficiency of 91%. If this pump is modified to operate at 1200 rpm, assuming its efficiency remains constant, determine its discharge, the theoretical head it imparts to the liquid and the power input to the pump.
A 25Hp suction pump operating at 56.30% efficiency draws water from a suction line whose diameter is 205mm and discharges into air through a line whose diameter is 155mm . The velocity in the 155mm line is 4m/s . If the pressure at point A in the suction pipe is -32kpa (negative sign indicate the pressure is below the atmosphere), where A is 1.8m below B on the 155mm line, determine the maximum elevation above B to which water can be raised assuming a head loss of 2.9m due to friction.
