A spherical raindrop that is D= 1/8 inch in diameter falls through the air at sea-level. a) If the raindrop reaches its terminal (constant) velocity when the drag force = weight, develop an equation for the terminal velocity VT= f(p H20, Pair, D, g, Cp) b) Estimate the drag coefficient on the raindrop using Table 7.3, White 8th edition and assuming laminar flow. c) Estimate the terminal velocity of the raindrop m/s d) Calculate the Reynolds number of the raindrop based on its terminal velocity

An incompressible fluid flows through a pipe that has two sections: a wide section with a diameterof 4 inches and a narrow section with a diameter of 2 inches. In which section of the pipe is thespeed of the fluid largest?a) both sections have the same speedb) the wide sectionc the narrow sectiond) which section has largest speed depends on the direction of flow

Fluids: hydraulic lift example (a) volume fluid displaced (b) output piston force (should be 48N) (c) radius of output piston

8- A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the deflection (the vertical distance between the fluid levels in the two arms) is 5.5 cm, determine the air Air velocity. Take the density of air to be 1.16 kg/m probe Pitot-static +5.5 cm Manometer
