Carbon-steel balls mm in diameter are annealed by heating
Chapter 7, Problem 147P(choose chapter or problem)
Carbon-steel balls \(\left(\rho=7833 \mathrm{~kg} / \mathrm{m}^{3} \text { and } c_{p}=0.465 \mathrm{~kJ} / \mathrm{g} \cdot{ }^{\circ} \mathrm{C}\right) 8 \mathrm{~mm}\) in diameter are annealed by heating them first to in a furnace and then allowing them to cool slowly to
in ambient air at
. If 2500 balls are to be annealed per hour, determine
the rate of heat transfer from the balls to the air and
the rate of entropy generation due to heat loss from the balls to the air.
