In a heat treatment of a specific excavator bucket tooth of 15kgmass, the tooth is heated to 8850C and to achieve therequired level of physical properties it needs to be cooled to thefinal temperature in a cooling tank using brine as the coolingmedium. Determine the final temperature if the minimum requiredmass of brine initially at 200C temperature is 260 kg,using specific heat values cb= 3.71 J/g·K andcs=0.47 J/g·K for brine and steel respectively. Assumeno heat losses to the environment.
