A stainless steel ball ( = 8055 kg/m 3 , c p = 480 J/kg.K) of diameter
Question:
A stainless steel ball (ρ = 8055 kg/m^{3}, c_{p} = 480 J/kg.K) of diameter D = 15 cm is removed from the oven at a uniform temperature of 350°C. The ball is then subjected to the flow of air at 1 atm pressure and 30°C with a velocity of 6 m/s. The surface temperature of the ball eventually drops to 250°C. Determine the average convection heat transfer coefficient during this cooling process and estimate how long this process has taken.
