Problem 2 (Textbook P7.8) Air, $\rho$ = 1.2kg/m³ and $\mu$ = 1.8 × 10??kg/(ms), flows at 10m/s past a flat plate. At the trailing edge of the plate, the following velocity profile data are measured: y, mm 0 0.5 1.0 2.0 3.0 4.0 5.0 6.0 u, m/s 0 1.75 3.47 6.58 8.70 9.68 10.0 10.0 Questions: (a) What is the boundary layer thickness, $\delta$? (b) What is the momentum thickness, $\theta$? (c) What is the friction drag per unit span ($F_{drag}$/b), in N/m, on the upper surface? (Hint: $F_{drag} = b \int_0^x \tau_w dx = bpU^2\theta(x)$.)

Consider a circular disc with the radius r with an axis stuck in a fork according to the figure. The disc rotates with a constant angular velocity ω relative to the fork in the given direction. At the same time, the arm of the fork OB rotates with a constant angular velocity ω around the vertical Z-axis and with a constant angular velocity ω around the X-axis in the given directions. The coordinate system Oxyz is fixed in the room, and the moving coordinate system's y-axis is always pointed along OB, and the z-axis is perpendicular to the surface of the disc. Determine the velocity and acceleration for the point A on the surface of the disc in the moment shown in the figure when the radius is perpendicular to OB, and the axes of the primed system are parallel to the axes of the unprimed system. b) Determine the moving system's angular velocity using ω = ωe + ωe1. Why isn't ω1 used and not ωe, and why is ωe used and not ωe1? c) Determine ω dot using ω1. Why is ω dot 0 even though ω and ω1 are constant?
