Question

hailstone is repeatedly carried aloft by the flow of a thunderstorm, each time growing in size and weight. The
temperature in the storm cloud is -10°C. At this temperature, the properties of the air and the ice are plair) = 1.341
kg/m, u(air) = 1.680E-5 kg/m-s, and p(ice) = 1000 kg/mº. After several cycles, the hailstone reaches a size where it can no
longer remain in the air. At the last cycle, the hailstone remains suspended and stationary for a few minutes before
dropping
Part A. Draw a diagram of the system and label the forces, features, and variables,
Part B. Briefly describe three flow approximations used to simplify the Navier-Stokes equation, and state which one
applies to this example.
Part C. Given these conditions and the expression for the assumed Navier-Stokes simplification, compute the largest
spherical hailstone diameter that can be held stationary by an updraft of U km/hr. it will be a very small diameter.
Confirm that this velocity and size satisfies the assumed approximation (hint: Uses Reynolds Number).
