Thermodynamics: Mass and Energy Analysis Of Control Volumes
Stainless steel ball bearings (ρ = 8085 kg/m3 and cp = 0.480 kJ/(kg◦C)) having a diameter of 1.5 cm areto be quenched in water at a rate of 900 per minute. The balls leave the oven at a uniform temperature of1000◦C and are exposed to air at 25◦C for a while before they are dropped into the water. If the temperatureof the balls drops to 900◦C prior to quenching, determine the rate of heat transfer from the balls to the air.

Both the room and the oil in theradiator are initially at 5◦C. The radiator with a rating of 3 kW is now turned on. At the same time, heatis lost from the room at an average rate of 0.3 kJ/s. After some time, the average temperature is measuredto be 20◦C for the air in the room, and 60◦C for the oil in the radiator.
