1. The problem statement, all variables and given/known data
I'm not too sure about my attempt to this question, but what is the simplified Steady Flow Energy Equation for a water pump that has one inlet at the bottom and one outlet at the top, and a work input?

2. Relevant equations
Q^ = W^ + m^[(h2 - h1) + 1/2 (c22 - c12) + g(z1 - z2)]

3. The attempt at a solution
I have attached a picture of my attempt to the solution to this thread.

Is there a question here?

Yes, my question, as stated already, is

My attempt to the solution along with the picture of what I'm talking about is attached too...as well as the steady-flow energy equation that I need to be simplified for this particular situation.

Yes. It looks like what you did is correct. With regard to the Δh, don't forget to include the Δp/ρ term.

@Chestermiller , okay, but isn't that already included, as h = u + pv ?

Yes. But some people would have just written Δh=CΔT. Since I don't know you, I was unaware of whether you might make that mistake.
