The airfl ow underneath an air hockey puck is very complex,especially since the air jets from the air hockey tableimpinge on the underside of the puck at various points nonsymmetrically.A reasonable approximation is that at anygiven time, the gage pressure on the bottom of the puck ishalfway between zero (atmospheric pressure) and the stagnationpressure of the impinging jets. (Stagnation pressureis defined as p0 =1/2ρV2jet . ) ( a ) Find the jet velocity V jetrequired to support an air hockey puck of weight W anddiameter d . Give your answer in terms of W , d , and thedensity ρ of the air. ( b ) For W = 0.05 lbf and d = 2.5 in,estimate the required jet velocity in ft/s.
An airplane is flying at 350 mi/h at 4000 m standard altitude. As is typical, the air velocity relative to the upper surface of the wing, near its maximum thickness, is 26 percent higher than the plane's velocity.
