3 Some temperatures are measured in degrees Rankine. Who was Mr. Rankine?

Exercise

In some US engineering textbooks dealing with temperature concepts, we find the mention of a temperature measured in a so-called Rankine scale. Very often, the relations between this temperature scale and those of Celsius, Fahrenheit and Kelvin are described by the respective conversion factors.

As with the other well-known temperature scales, it seems that this scale was named after a certain Mr. Rankine.


Questions for  open discussion

  • Who was Mr. Rankine?

    Does this Rankine scale have something in common with the Kelvin scale?

    What must do this Rankine scale with other temperature scales like Fahrenheit and Celsius?

    What are the Absolute Temperature scales useful for?

    What are the advantages of the Absolute Temperature scales with respect to the ordinary scales?

    Which is the present use of the Rankine scale?
