Terminal velocity

The Physics Teacher, 1999
Authors re-examine Paul Hewitt’s question in a past “Figuring Physics”: When a Ping Pong ball dropped from the top of a high building reaches terminal speed, its acceleration is zero. Now suppose the ball is projected upward with an initial speed greater than this terminal speed.

The College Mathematics Journal, 2013
SummaryUsing a simultaneously falling softball as a stopwatch, the terminal velocity of a whiffle ball can be obtained to surprisingly high accuracy with only common household equipment.

Terminal velocity of porous spheres

The Canadian Journal of Chemical Engineering, 1980
AbstractTerminal velocity of porous spheres was experimentally measured for a Reynolds number range of 0.2 to 120 for anormalized sphere radius, β = R/R of 15.6 to 33, where R and k are the sphere radius and permeability, respectively. The drag coefficient for 15 < β < 33 was found to be CD = 24Ω/Re [1 + 0.1315 Re(0.82 ‐ 0.05w)] for 0.1 < Re ≤

Critical and terminal velocities in fluidization

Chemical Engineering Science, 1956
Abstract Critical fluidization and terminal velocities of spherical and nonspherical particles were determined in nitrogen. The ratios of these velocities, or of their particle Reynolds numbers, are shown to be function of the dimensionless group The ractical implications of the results are discussed.

The terminal velocity of snowflakes

Quarterly Journal of the Royal Meteorological Society, 1954
AbstractMeasurements of the terminal velocity of aggregate snowflakes at the ground indicate that the velocity is approximately proportional to the one‐tenth power of the mass. The constant of proportionality is dependent on the basic crystal types in the aggregates. It is moreover greatly increased by riming or by slight melting of the snowflakes.When

The terminal velocity of drops

Proceedings of the Physical Society, 1927
The distance a drop of given volume has to fall through in order that it may attain a constant terminal velocity has been determined for both water and methyl salicylate. A relation connecting the distance of fall for constant velocity and the volume of the drop has been obtained.

Terminal velocity of skydivers

Physics Education, 2000
The expression for the terminal velocity of skydivers in the horizontal spreadeagle position is shown to be somewhat insensitive to the mass of the diver. However, the fact that it does depend upon the density of the medium is shown by one numerical illustration.
