Cylinders of various length-diameter ratios were accelerated vertically with constant drive forces; correlation between coefficient of resistance and acceleration modulus using Reynolds number and length-diameter ratio as parameters was found to exist; experimental arrangement resembled Attwood's machine; lateral displacement of cylinder was restrained during acceleration.
