Question 35
XE-BMCQ2 marksNeeds review
Consider a steady, laminar, and incompressible flow over a flat plate, as shown in the figure. With freestream velocity
and kinematic viscosity
, the boundary layer thickness at a distance
from the leading edge is
. If the kinematic viscosity of the fluid is increased by a factor of four (
), the boundary layer thickness (
) at
with same
will be equal to
