A metal part is undergoing a heat-treating process, it has a
mass of 12 kg and is initially at 950∘C. The part is quenched in a
tank containing 225 kg of water, initially at 35∘C. Consider the
heat transfer between the tank and its surroundings to be
negligible. Taking the specific heat of the metal part and water as
constant at 0.5 kJ/kg.K and 4.2 kJ/kg.K respectively, determine :
The final equilibrium temperature after quenching Tf= ∘C The amount
