Question 37
XE-BNAT2 marksNeeds review
Consider two-dimensional turbulent flow of air over a horizontal flat plate of length 1 m. Skin friction coefficient at a length
from the leading edge of the plate is obtained as:
where,
is the local Reynolds number.
Find out the drag force per unit width (in N/m
) on the plate if the free stream air velocity is 10 m/s.
Density and dynamic viscosity of air are given as 1.2 kg/m
and
N-s/m
, respectively.
