Homework Statement


Is this equation correct for the 1st Law of Thermodynamics for an Open System (Control Volume):
Q - W + min(h + 1/2(c^2) + gz)in - mout(h + 1/2(c^2) + gz)out = Δ(U 1/2(c^2) + gz).


Homework Equations


None really.



The Attempt at a Solution


This isn't so much an assignment question as a possible discrepancy in the notes. I would've thought this Δ(U 1/2(c^2) + gz) should be Δ(U 1/2(mc^2) + mgz), am I correct in thinking that or not? Thanks.
