5.4 Water flows out through a set of thin, closely spaced blades as shown in Fig. P5.4 with a speed of V = 10 ft/s around the entire circumference of the outlet. Determine the mass flowrate through the inlet pipe.

5.15 (WILEYa Water at 0.1 m/s and alcohol (SG = 0.8) at 0.3 m²/s are mixed in a y-duct as shown in Fig. 5.15. What is the average density of the mixture of alcohol and water? Water and alcohol mix Water Q = 0.1 m³/s Alcohol (SG = 0.8) Q = 0.3 m3/s Figure P5.15

5.28 A circular plate having a diameter of 300 mm is held per- pendicular to an axisymmetric horizontal jet of air having a veloc- ity of 40 m/s and a diameter of 80 mm as shown in Fig. P5.28. A hole at the center of the plate results in a discharge jet of air having a velocity of 40 m/s and a diameter of 20 mm. Determine the hor- izontal component of force required to hold the plate stationary. 40 m/s 80 mm -Plate 20 mm FIGURE P5.28 40 m/s
