Unformatted text preview: ction in the rate of entropy generation in the resistance heating section. 7–174 In order to cool 1-ton of water at 20°C in an insulated tank, a person pours 80 kg of ice at 5°C into the water. Determine (a) the final equilibrium temperature in the tank and (b) the entropy generation during this process. The melting temperature and the heat of fusion of ice at atmospheric pressure are 0°C and 333.7 kJ/kg. 7–175 An insulated piston-cylinder device initially contains 0.02 m3 of saturated liquid–vapor mixture of water with a quality of 0.2 at 100°C. Now some ice at 5°C is dropped into the cylinder. If the cylinder contains saturated liquid at 100°C when thermal equilibrium is established, determine (a) the amount of ice added and (b) the entropy generation during this process. The melting temperature and the heat of fusion of ice at atmospheric pressure are 0°C and 333.7 kJ/kg.
