Question

Experiments have been conducted to determine local heat transfer coefficients for flow perpendicular

to a long, isothermal bar of rectangular cross section. The bar is of width c, parallel to the flow, and height

d, normal to the flow. For Reynolds numbers in the range 4 4 10 5 10 ? Re x d

? , the face-averaged Nusselt

numbers are well correlated by an expression of the form.

The values of C and m for the front face, side faces and back face of the rectangular rod are found to be

the following:

Determine the value of the average heat transfer coefficient for the entire exposed surface (that is,

averaged over all four faces) of a c mm 40 ? ? wide, d mm 30 ? ? -tall rectangular rod. The rod is

exposed to air in Cross-flow at V msT K 10 / , 300 ? ? ?

. Provide a plausible explanation of the

relative values of the face-averaged heat transfer coefficients on the front side and back faces.

Sorry, I couldn't enter the equation or chart.

please post the question clearly.i am not able to see the units ans values.
