Air enters a fan through a duct velocity of 6.3 m/s and an inlet static pressure of 2.5cm of water less than the atmospheric pressure. The air leaves the fan through the duct at a velocity of 11.25 m/s and a discharge pressure of 7.62cm of water above the atmospheric pressure. If, the density of the air is 1.2kg/m3and the fan delivers 9.45m3/s, what is the fan efficiency when the power input to the fan is 13.75 kW at the coupling. Show schematic diagram and provide solutions.
A 3-cm-diameter horizontal pipe attached to a surface makes a 90° turn to a vertical upward direction before the water is discharged at a velocity of 9 m/s. The horizontal section is 5 m long and the vertical section is 4 m long. Neglecting the mass of the water contained in the pipe, the bending moment acting on the base of the pipe on the wall is (a) 286 N·m (b) 229 N·m (c) 207 N·m (d) 175 N·m (e) 124 N·m
0il with p = 876 kg/m³ and u = 0.24 kg/m-s is flow- ing through a 1.5-cm-diameter pipe that discharges into the atmosphere at 88 kPa.

Determine the flow rate of oil through the pipe if the pipe is (a) horizontal, (b). inclined 8° upward from the horizontal, and (c) inclined 8° downward from the horizontal.
A fluid moves in a steady flow manner between two sections in a flow line. At the entrance section A1 = 1m², V1= 0.5 m/s, P1= 4kgm/m³. At the exit section: A2 = 0.2m², V2= 0.20m³/kgm. Calculate the mass flow rate in kg/s and the speed at section 2 in m/s.

In a centrifugal blower (Figure Q1) air enters in to the blower normal to the blades (a1 = 0°), and exits at 40°from the radial direction (∞2=40°). The blower rotates at w = 200 rad/s. The inlet radius r1 = 4 cm, and inlet widthb1 = 6 cm. The outlet radius r2 = 10 cm and outlet width b2 = 3 cm. Assuming 100% etticiency and considering 0.2m3/s flow rate, calculatea) the net head produced by the blowerb) the breaking horsepower in watt.(Take density of air Pair = 1.2 kg/m', gravity, g = 9.81 m/52)
Q6) (a) Two sites are being considered for wind power generation. In the first site, the wind blows steadily at 7 m/s for 3000 hours per year, whereas in the second site the wind blows at 10 m/s for 2000 hours per year. Assuming the wind velocity is negligible at other times for simplicity; determine which a better site is for wind power generation. Hint: Note that the mass flow rate of air is proportional to wind velocity. (Take the density of air to be ? = 1.25 kg/m3).
In a hydraulic installation, the water flows through a duct of 3 cm in diameter with a speed of 0.65 m/s; At the outlet of the duct there is a 0.3 cm diameter nozzle. If the nozzle, discharge the water to the conditions of the CDMX (???? = 77 ???, ? = 9.78 ? /?2 ), determine: a) The speed of the water when it leaves the nozzle b) If a pump is installed just before the duct inlet, and the duct inlet and outlet are at the same height. What is the fluid pressure at the pump outlet?
Water is flowing through a 15-cm-diameter pipe that consists of a 3-m-long vertical and 2-m-long horizontal section with a 90° elbow at the exit to force the water to be discharged downward, as shown in Fig. P6–55, in the vertical direction. Water discharges to atmospheric air at a velocity of 5 m/s, and the mass of the pipe section when filled with water is 17 kg per meter length. Determine the moment acting at the intersection of the vertical and horizontal sections of the pipe (point A). What would your answer be if the flow were discharged upward instead of downward?
A 90° elbow is directs water upwards into the atmosphere from a horizontal pipe with a diameter of 12 cm that is flowing at 20 L/s. The elevation difference between the centers of the exit and the inlet of the elbow is 35 cm. If the weight of the elbow and the water in it are negligible, and assuming a momentum-flux correction factor of 1.03, determine the anchoring force needed to hold the elbow in place.
What is steady flow and unsteady flow through an orifice?
The impeller of a centrifugal blower has a radius of 18 cm and a blade width of 6.1 cm at the inlet, and a radius of 30 cm and a blade width of 3.4 cm at the outlet. The blower delivers atmospheric air at 20°C and 95 kPa. Disregarding any losses and assuming the tangential components of air velocity at the inlet and the outlet to be equal to the impeller velocity at respective locations, determine the volumetric flow rate of air when the rotational speed of the shaft is 900 rpm and the power consumption of the blower is 120 W. Also determine the normal components of velocity at the inlet and outlet of the impeller.
