To examine usefulness of a personal computer, the M-Draf 16 and M-Draf 32 with their 2-D CAD systems in designing the practical machines at industries, a standard heat-exchanger of multitubular cylindrical type having the generating surface area from 30m^2 to 250m^2 was designed. The necessary material's date are filed in a floppy disk from which the require data can be easily selected for variations in the design. Basic equations and conditions in designing the above machine parts are programed in a system by which the major design calculations are carried out nearly automatically. In addition to this, the detailed design calculation programs are also filed in the system. Thus all the designed data for the heat-exchanger are printed out by giving the necessary input data to the program. The M-Draf 16 with it's 2D-CAD system is operated with these designed data and the two-dimensional machine parts are drafted. By use of recently provided the M-Draf 32 with it's 2D-CAD system the above design is followed. The details of the designed data and the drafts of the heat-exchanger are presented and the usefulness of the above personal computer systems are discussed.
