## Abstract Measurements have been made of the speeds of ice objects resembling hailstones during free fall, and of the drag coefficients of such objects and of natural hailstones. It has been found that the drag coefficients range from those of spheres (about 0ยท45) to about 0ยท8, depending on the s
## Abstract By measuring the rate of melting of spheres and oblate spheroids of ice in an airstream, the dependence of the rate of heat transfer on shape has been determined. Applying the results to hailstones, it has been found that, in terms of the maximum dimensions of the stones, melting is mor
