A steel drill rod that is 10 mm in diameter and 20 cm long is being heat treated in an oil bath. The 1050°C rod is quenched and held at 700°C and then quenched a second time to 30°C. Calculate the quantities of heat that must be removed at the two quenching stages. Weight density of steel as ρw = 76 kN/m3 , The specific heat of steel is c= 0.50 kJ/(kg . ºC).
