(40 pts) The drag force exerted on an automobile running at a constant speed of 30 m/s is to be determined by running flow tests on a 1/6 scale model in a water tunnel. The drag force is known to be a function of the characteristic length, L, describing the vehicle frontal section, the vehicle speed relative to the fluid, V, and the fluid density and viscosity. Dimensional analysis has shown the following dimensionless relationship: Cp = º(Re), where FD...

A fire helicopter carries a 967 kg bucket at the end of a cable 19 m long as in the figure. As the helicopter flies to a fire at a constant speed of 50 m/s, the cable makes an angle of 4dº with respect to the vertical. The bucket presents a cross sectional area of 6.03 m in a plane perpendicular to the air moving past it. Use 1.2 kg/m for the density of air. The acceleration of gravity is...

The construction of a water pistol is shown in the figure below. The cylinder with cross-sectional area A, is filled with water and when the piston is pushed (by pulling the trigger), water is forced out the tube with cross-sectional area A. The radius of the cylinder and tube are, respectively, 1.40 cm and 1.50 mm, and the center of the tube is a height h = 3.00 cm above the center of the cylinder. (Assume atmospheric pressure is 1.013...
