During air cooling of steel balls, the convection heat transfer coefficient is determined experimentally as a func- tion of air velocity to be h 17.9v054 for 0.5 < v< 2 m/s, where h and v are in w/m2.k and m/s, respectively. consider a 24-mm-diameter steel ball initially at 300°c with a thermal conductivity of 15 w/m-k. the steel balls are cooled in air at 10°c and a velocity of 1.5 m/s. determine the initial values of the heat flux and the temperature gradient in the steel ball at the surface.
