The movement of a sphere in a liquid is a hollow steel tube with a mass of 0.07 g and a diameter of 6 mm.
The sphere is dropped into a column of liquid. The sphere reaches a terminal velocity of 0.80 cm/s. of the liquid
density 1.2 gr/cm3
and the gravitational acceleration at that place is 981 cm/s2
is . Sphere on the walls of the vessel
sufficiently far away, the wall effects are negligible. 1). Drag force as dyn
calculate, 2). Calculate the drag coefficient.
