Water temperature influence on the spherical body's falling velocity

Augmentation of the falling velocity did not correspond directly on the body's temperature growth. There existed an appropriate interval of the body's surface temperature for which the falling velocity was the highest. Difference between the falling velocity of the hot and cold bodies increased gradually with the rise of the falling time and reached 25% for the stainless steel sphere which temperature was 410 °C and water temperature was 14 °C.
