Web1 day ago · He's got the speed (4.54 40-yard dash), leaping ability (36.5-inch vertical), and catch-and-run skills to be a big slot, occasionally lining up at tight end to be a mismatch on interior linebackers. Typically, due to aerodynamic drag, there is a wind gradient in the wind flow, especially in the first few hundred meters above the Earth's surface—the surface layer of the planetary boundary layer. Wind speed increases with increasing height above the ground, starting from zero due to the no-slip condition. Flow near the surface encounters obstacles that reduce the wind speed, and introduce random vertical and horizontal velocity components at right angles to the main directio… eg25 micro smoke grenade
