Question 54
CHNAT2 marksNeeds review
A fluid is flowing steadily under laminar conditions over a thin rectangular plate at temperature
as shown in the figure below. The velocity and temperature of the free stream are
and
, respectively. When the fluid flow is only in the
-direction,
is the local heat transfer coefficient. Similarly, when the fluid flow is only in the
-direction,
is the corresponding local heat transfer coefficient. Use the correlation
for the local heat transfer coefficient, where, Nu, Re and Pr are the appropriate Nusselt, Reynolds and Prandtl numbers. The average heat transfer coefficients are defined as
and
. If
m and
m, the value of the ratio of
to
is ______ (in integer).
