The can diameter and height are D = 65 mm and H = 120 mm. The can is halffull of soda, with specific gravity SG = 1.06. Assume rigid body motion. A. Find the slope of the liquid surface in the can if the merrygoround spins at 0.3 revolution per second. B. Find the spin rate at which the can would spill, assuming no slippage between the can bottom and the merrygoround. KAIST Department of Mechanical Engineering MAE 221 A/B/C 2010 Fall Semester Problem 2 (20 points): Water from a stationary nozzle strikes a flat plate as shown. The water leaves the nozzle at 15 m/s; the nozzle area is 0.01 m 2 . Assuming the water is directed normal to the plate, and flows ....
