Homework Statement

Homework Equations

P=F*V, dU=Q-W?, W=m(h1-h2)

The Attempt at a Solution

I have the initial conditions and final conditions written out. For W=m(h1-h2), I have W=9.48(h1-h2). I am having problems with the h values, which can be found in the steam tables.

It might be helpful if you could tell us what kind of problems you are having with the steam tables. Also, why are you using the volumetric flow rate in your equation, when your Relevant Equation calls for mass flow rate. Also, from the way that this problem is posed, it seems that you are expected to include the change in the kinetic energy. Are you aware that you are supposed to be using the steady state open system version of the first law of thermodynamics on this problem? If so, please include it in the relavant equations.
