Do not add additional methods to the Die or PairOfDice classes. The data about the rolls is not being stored so there is no need to create an array. Remember to keep the methods simple. The methods should be designed to do one thing only. This helps the classes and methods have high cohesion. Our projects will follow the principles of modularity covered in CIS 2110. You can write test code to test the methods of the Die class before creating the PairOfDice class but remember to remove it from the program because only the PairOfDice class is called from the DiceRollerApp class.

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.
