Treatise on intake systems

[James Boughton]

I'm sorry about using g for gamma, but I don't have a gamma
on my keyboard and g looked like the closest thing:-)  I guess
I should have explained myself, sorry!  

According to table D.1 of Heywood's "Internal Combustion
Engine Fundamentals" gamma does change with temperature,
however, you are correct regarding the gas constant which
does not.  I guess that is why they call it a constant:-)  I was
noting that the specific heats change with temperature and
wasn't thinking.  Again, sorry!

Thank you for the corrections.

(The speed of sound is simply (gRT)^0.5 where g and R are considered
constant.  If you wanted to be rigorous you could actually vary g and R
for temperature, but probably not worth it.)

Jim:  I have a question....how can g (is this gravitational constant?) and
R (the universal gas constant) vary with temperature?
