A sel A. soA A solid cylinder of diameter d, length and
density p. falls due to gravity inside a pipe of diameter D.
The clearance between the solid cylinder and the pipe is filled
with a Newtonian fluid of density p and t. For this clearance
fluid, the terminal velocity of the cylinder is determined to
be F, assuming a linear velocity profile. However, if the
clearance fluid was changed to a Newtonian fluid of density
2p and viscosity 2u, then for an assumed linear velocity
profile, the terminal velocity of the cylinder was determined
to be . From the results of these experiments. one may
write that
(A) V, =
(C) 2 V = V,
(B) V= 2 V,
(D) F= 4 V,
