The Coriolis Force Did Zero Work, Yet the Impeller Added 1800 J/kg — Energy in a Rotating Frame
·7 min read
What a rotating frame conserves is rothalpy, not total enthalpy. Here is why the Coriolis force never does work on the fluid, and where a pump's head actually comes from, checked numerically.
