Consider two cases involving parallel flow of dry air at v = 1.0 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 × 10^5 , 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?

During takeoff, the sound intensity level of a jet engine is 170db at a distance of 34 m. what's the sound intensity level at a distance of 1.0 km?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
