Circular copper rods of diameter D=1mm and length L=25mm areused to enhance heat transfer from a surface that is maintained atTs,1=100 deg.C. One end of the rod is attached tothis surface (at x=o), hile the other end (at x=25mm) is joined toa second surface that is maintained at Ts,2=0deg.C. Air flowing between the surfaces (and over the rods)is also at a temperature T∞= 0 deg. C, and has a convectioncoefficient of h=100 w/m2kelvin.
What is the rate of heat transfer by convection from a singlecopper rod to air?
