Hello !
I am having a bit of trouble understanding something about exergy.
On one hand, I read that (1-Ta/Tc)*Q (exergy heat) is the maximum work given a heat transfer and a reservoir's temperature.
But from the other hand, I read that this exact same (1-Ta/Tc)*Q represents losses. ( Which i can also understand, if Tc is high, then the losses to the atmosphere will be higher due to the higher Heat transfer).
Does the two affirmations are true ? How ?
Thank you !
