A sphere of plain carbon steel is ½" in diameter. It is annealed
by heating to 1600° F and then
slowly cooling to 250° F in an air environment for which the
ambient temperature is 125° F and the
convective heat transfer coefficient is 3.5 Btu/hr ft? °F.
Calculate the characteristic length for this
body. How does it compare with the diameter of the sphere? Which
is a more appropriate choice in
your calculations? Estimate the time required for this cooling
process.
