A two-dimensional airfoil (object 1) is subject to air flow of upstream velocity 28 m/s. The upstream air pressure and temperature are 0.4 atm and 280 K, respectively. The characteristic length of object 1 is 25 mm and its surface temperature is uniform at 320 K. Now, a geometrically similar airfoil (object 2) with different characteristic length 167 mm is placed in water flow. The upstream water temperature is 300 K and the surface temperature of object 2 is uniformly at 310 K. What is the upstream water velocity in m/s for object 2 such that the boundary layer analogy exists between the two cases? Note that liquid water properties can be approximated as those for a saturated liquid at the same temperature. Object 1 Tsl Air Tool V₁ Li Water Too2 V₂ Object 2 L₂ T₁2

Air Ta = 0°C D Is Ясоnd A liquid water droplet of diameter D = 255 µm falls on a cold surface with temperature T, = -3°C. During phase change the droplet maintains a constant temperature Ta = 0°C. If the latent heat of fusion hsf = 334 for water, how much time tf does it take the droplet to freeze? Assume the drop does not deform and the only heat transfer is by conduction. The air has thermal conductivity k = 0.024 W %3D kg m-K Hint: The restrictions for Case 1 in Table 4.1 should really read z > D/2. The implication is that the droplet center can't be less than a radius away otherwise the droplet shape would deform away from spherical and the shape factor would no longer be valid. tf = 8 (3 sig figs)
