Identify the purpose of flowcharts. Check all that apply. Flowcharts highlight the errors in a program.
Flowcharts help us see how the program works and what results are intended.
Knowing the complete process flow from the start helps the programmer create a computer program
that will solve the problem.
Flowcharts provide an idea of what data is needed at each point in the program.

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.
