This is an old text book but still very relevant.  I've always liked
stuff by Burghardt for two reasons.  The math he presents is
straight-forward algebra and doesn't leave you glassy-eyed.  He uses
'English' units with the lb-force and lb-mass convention, which is what
I first started out with.

There's a good section on gas laws and various 'processes'.  And lots of
information in the appendices.  One area it's a bit 'light' in is the
heat-transfer stuff, but it does cover the basics of that as well.

Heh! Straight-forward algebra sounds good 'cause I'm not allowed to haze
out on math.

I'm doing my level best to stick to SI units, so what amounts to an "old
friend" to you is sheer aggravation for me. I suppose I should learn to
be comfortable with both, but doubt I can manage that _and_ actually
solve the problems in front of me...

I've bookmarked it. The books already en route are

"Thermodynamics" by Wark and Richards, and

"Steam Tables: Thermodynamic Properties of Water Including Vapor, Liquid
and Solid Phases" by Hill, Keenan, Moore, and Keyes

...and I'm already at the point where putting another book on the shelf
means that one of the books already there has to go. :(

Wouldn't it be great if someone developed a gizmo that ate paper books
and spit out e-books on flash memory sticks? (Even better if
high-lighting and marginal notes were preserved!) :)

Peace, health, prosperity, and sunshine to you.

I also have "Thermodynamics: 4th Edition" by Wark (1983).  Don't know if
it's exactly the same one, it doesn't mention a 'Richards'.  I've got
about five different thermo books and a couple of heat-transfer ones.

The steam tables I've always used were put out by Combustion Engineering
in a pamphlet form (but the forwards says they are based on Keenan and
Keyes (1968)).  Love all the conversion factors in the back :-)

Know what you mean about bookshelf space.  We just moved from NY to TN
and I was forced to unload a lot of books.  Figured if I hadn't opened
it in ten years, it was fair game.  Predictably, Burghardt and Wark
didn't fit that category.

I'm sort of gummed up with some of my distillation calculations,
mainly for water to water and maybe oil to water heat exchangers
(re-biolers) and vapor to water condensers. Could you recommend a good
heat-X book with completed math examples in imperial units?

I have one at work, will look up the biblio on it next week when I'm
back at work.

IIRC, condensers are *majorly* affected by even traces of
non-condensable gasses (i.e. air).  Tends to build up as a boundary
layer on the cooling surface and then you're limited by diffusion of
vapor through the film layer of air.

This is why steam condensers have the air-removal system suction
embedded in the middle of the tube bundle (sometimes called a 'dry pipe
suction').  Taking suction from the coldest spot improves the
air-fraction in the suction flow.
