Question 20
XE-BNAT2 marksNeeds review
In a steady incompressible flow of a fluid past a smooth stationary sphere, the drag force
depends on the flow velocity
, diameter
, and the dynamic viscosity
and density
of the fluid. Experiments are conducted on the same sphere at the same flow velocity using two different fluids. The density of the second fluid is two times that of the first fluid. The dynamic viscosity of the second fluid is
times that of the first fluid. If the non-dimensional force
remains the same in both the experiments, the value of
is ______.Log in to check the answer
