Turbocharger Compressor Map Calculation

Speed-Wiz can display turbocharger compressor flow maps and calculate flow rates and pressure ratios and plot them on the compressor map. Several compressor maps are included, and it's easy to add your own compressor maps as shown below.

As the calculation window is resized, the compressor map is also resized to be displayed as large as possible.
