* 4. Annika’s class is investigating energy. They wonder what would happen to the temperature reading on a thermometer if they put the thermometer inside a mitten (see diagram A above). Both thermometers started at room temperature. Annika’s group obtained two thermometers and a mitten. They put one thermometer inside the mitten and the other thermometer on the table next to the mitten. An hour later they compared the readings on the two thermometers. The temperature inside the room remained the same during their experiment. The thermometer inside the mitten will have a lower temperature reading than the thermometer on the table because the mitten will conduct the cold air outside the thermometer. Both thermometers will have the same temperature reading because the mitten doesn’t generate additional heat. The thermometer inside the mitten will have a higher temperature reading than the thermometer on the table because the mitten will trap the warm air inside the mitten. The thermometer inside the mitten will have a higher temperature reading than the thermometer on the table because the mitten will insulate the thermometer.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
