Mr. Slim Shady is a well-known blacksmith, an expert on making kitchen knives. He is currently working on a project for the President of Indonesia. He prepares a 1.2 kg metal bar (iron) initially at 800C. The metal bar is removed from an oven an quenched inside a 30cm x 35 cm x 25 cm tank full of oil at 23C. The oil can be assumed to be incompressible fluid. Heat transfer from the tank to the surroundings can be neglected. Determine the final equilibrium temperature of the metal bar and the oil inside the tank, in C and the amount of entropy produced, in kJ/K.
