Water is well mixed in a 1m3 vessel. A stirrer introduces 300W of power into the vessel. The heat transfer from the tank to the surroundings is proportional to the temperature dissimilarity between the vessel and the surroundings (at 20oC).The flow rate of liquid in and out of the tank is 1Kg/min. If the temperature of the inlet liquid is 40oC, determine what is the temperature of the outlet liquid? The proportionality constant for the heat transfer is 100W/oC.
