Transcribed Image Text:

A 0.3 kg of metal bar initially at 1200 K is immersed in a closed tank containing 9 kg of water initially at 300 K (refer to the diagram below). Each substance can be modeled as incompressible. The specific heat value for the water is Cw = 4.2 kJ/(kg.K) and the specific heat value for the metal is Cm= 0.42 kJ/(kg.K). Heat transfer through the tank wall can be neglected. Determine: (a) the final equilibrium temperature of the metal bar and water, in K, and (b) the amount of entropy produced, in kJ/K. -System boundary Metal bar: Tmi Cm = 0.42 kJ/(kg.K) mm = 0.30 kg 1200 K Water: Twi <= 300 K Cw= 4.2 kJ/(kg.K) m = 9 kg A 0.3 kg of metal bar initially at 1200 K is immersed in a closed tank containing 9 kg of water initially at 300 K (refer to the diagram below).
