Steam at a temperature of 623 K is flowing through a pipe with an outer diameter of 100 mm. The pipe is insulated with 20-mm thick mineral wool, the average thermal conductivity of which is 0.055 W/m.K. Determine the outside surface temperature of mineral wool if the ambient air temperature is 300 K. Assume the hot-surface temperature of the mineral wool is the same as that of the flowing steam and the value of the surface coefficient of the insulating material is 30 W/m2.K.

Write a function in this file called nine_lines that uses the function three_lines (provided below) to print a total of nine lines.
Now add a function named clear_screen that uses a combination of the functions nine_lines, three_lines, and new_line (provided below) to print a total of twenty-five lines. The last line of your program should call first nine_lines and then the clear_screen function.
The function three_lines and new_line are defined below so that you can see nested function calls. Also, to make counting “blank” lines visually easier, the print command inside new_line will print a dot at the
