) Stainless steel ball bearings (ρ = 8085 kg/m3 and cp = 0.480 kJ/kgC) having a diameter of 1.22 cm are to be quenched in water at a rate of 1402 per minute. The balls leave the oven at a uniform temperature of 900C and are exposed to air at 300C for a while before they are dropped into the water. If the temperature of the balls drops to 855 C prior to quenching, determine: (i) The rate of heat transfer from the balls to the air; and (ii) The rate of entropy generation due to heat loss from the balls to the air.

Question
) Stainless steel ball bearings (ρ = 8085 kg/m3
and cp = 0.480 kJ/kgC) having a
diameter of 1.22 cm are to be quenched in water at a rate of 1402 per minute.
The balls leave the oven at a uniform temperature of 900C and are exposed to air at 300C for a while before they are dropped into the water. If the
temperature of the balls drops to 855
C prior to quenching, determine:
(i) The rate of heat transfer from the balls to the air; and
(ii) The rate of entropy generation due to heat loss from the balls to the air.
