This spreadsheet uses vectors available within Excel’s drawing tools for the numerical/graphical analysis of a single stage of an axial flow compressor.  The user merely needs to set up an array of four cells holding the x and y coordinates of the head and tail of each vector they wish to display.

Here the blue vector is proportional to the tangential velocity and the red vector represents the throughflow velocity.   The relative (yellow) and absolute velocities (green) complete the vector plot.  Such a display can be very useful in a turbomachinery or jet engines course.   Included in this workbook is a graphic showing a fully-worked out example including the rotor inlet (above), outlet and combined velocity triangles.
