In a heat treatment of a specific excavator bucket tooth of 15kg mass, the tooth is heated to 885⁰C and to achieve the required level of physical properties it needs to be cooled to the final temperature in a cooling tank using brine as the cooling medium. Determine the final temperature if the minimum required mass of brine initially at 20⁰C temperature is 260 kg, using specific heat values c_b= 3.71 J/g·K and c_s=0.47 J/g·K for brine and steel respectively. Assume no heat losses to the environment.
