That is a very "pure physics" way to approach physics, and I think it's right if you want to build up the underlying principles. That was how my college taught

That is a very "pure physics" way to approach physics, and I think it's right if you want to build up the underlying principles. That was how my college taught physics, and it helped to make many otherwise unintuitive parts of thermodynamics understandable. Also, physicists don't necessarily include fluid dynamics as a core discipline. It is almost mechanical engineering to them. I'm not surprised to see it missing.
