Hail terminal velocity
Did you know?
WebTerminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid ( air is the most common example). It occurs when the sum of the drag force ( Fd) and the buoyancy is equal to the downward force of gravity ( FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration ... Weband hail terminal velocities as a function of their size (maximum dimension). The goal of our study is to im-prove these estimates, thereby leading to improved representations for …
WebFeb 27, 2007 · Assume the hail is at terminal velocity(not accelerating), therefore drag is equal to -mg. Set equal and solve for velocity. Assume spherical with drag coefficient … WebAnswer: Terminal velocity is a function of air resistance vs weight. The greater an object’s weight the greater its terminal velocity, however the greater an object’s air resistance the lower its terminal velocity. Because air resistance is primarily a function of the surface area of the object (...

The size of hailstones is best determined by measuring their diameter with a ruler. In the absence of a ruler, hailstone size is often visually estimated by comparing its size to that of known objects, such as coins. Using the objects such as hen's eggs, peas, and marbles for comparing hailstone sizes is imprecise, due to their varied dimensions. The UK organisation, TORRO, also …
