In the following figure, a machine is installed in the water drainage system. Knowing that the machine's efficiency is 75%, obtain the flow direction, whether the machine is a pump or a turbine and its power. The pressure measured by the manometer above the machine is equal to 150 kPa and the pressure loss is given by lw= K* u2b / 2(m2/s2). Between sections (1) and (2), K1-2 = 3.0, and between sections (2) and (3), K 2-3 = 1.5. D = 15 cm, ρ= 103 kg/m3 and 1HP = 745,7 W (watt)

Question
In the following figure, a machine is installed in the water drainage system. Knowing that the machine's efficiency is 75%, obtain the flow direction, whether the machine is a pump or a turbine and its power.
The pressure measured by the manometer above the machine is equal to 150 kPa and the pressure loss is given by lw= K* u2b / 2(m2/s2). Between sections (1) and (2), K1-2 = 3.0, and between sections (2) and (3), K 2-3 = 1.5.
D = 15 cm, ρ= 103 kg/m3 and 1HP = 745,7 W (watt)
