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)

Air is kept in a tank at pressure Po = 689 KPa abs and temperature To = 17°C. If one allows the air to issue out in a one-dimensional isentropic flow, the flow per unit area at the exit of the nozzle where P = 101.325 KPa is Blank 1 kg/m2-s. For air, Use R = 287 J/kg-K and Mol. Wt. = 29.1 *Express your answers in whole significant figure without decimal value and without unit*
Water flows through an orifice at the vertical side of a closed cylindrical tank. The water level inside the tank remains constant at 3m and the pressure at the top of the tank is 30KPa. If the jet strikes the ground horizontally by 4.5m and below the vena contracta by 1m, determine the coefficient of velocity.
