7.11 Consider two cases involving parallel flow of dry air at V = 1 m/s, T_∞ = 45°C, and atmospheric pressure over an isothermal plate at T_s = 20°C. In the first case, Re_x,c = 5 × 10⁵, while in the second case the flow is tripped to a turbulent state at x = 0 m. At what x‐location are the thermal boundary layer thicknesses of the two cases equal? What are the local heat fluxes at this location for the two cases?

Answer: x=.142; q”_lam = -129 W/m²; q”_turb = -175 W/m²

V = X'(t) = -t^2 + 6 m/s Implies X(t) = -(1/3)*t^3 + 6*t The initial position is zero in this case. This function will initially increase (this means the object is moving forward), then the negative force will be too strong, so the object will start moving backwards. calculate the maxima and minima. Graph the function X(t). Describe the motion. Every detail.

An aircraft is in level flight at airspeed v(t) m/s with thrust T(t) N at cruising altitude. Suppose that at v0 = 250 m/s, the aerodynamic drag experienced by the aircraft at this altitude is: Fd(v) = 0.25v 2 .
