1st Law of Thermodynamics (Open System)

[SherlockOhms]

Homework Statement

Is this equation correct for the 1st Law of Thermodynamics for an Open System (Control Volume):
Q - W + m_in(h + 1/2(c^2) + gz)_in - m_out(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.
