Write an application containing three parallel arrays that hold 10 elements each. the first array hold four-digit student id numbers, the second array holds first names, and the third array holds the students’ grade point averages. use dialog boxes to accept a student id number and display the student’s first name and grade point average. if a match is not found, display an error message that includes the invalid id number and allow the user to search for a new id number.

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.
