Unformatted text preview: table, superheat table & compressed liquid table. • Ideal gas: pv = RT & tables for u(T), h(T), s (T), p r & v r or the constant specific heat relationships. • Non-ideal gas and compressibility factor. Step 4: • Locate process end points on p-v and/or T-s diagrams and for quasi-equilibrium processes the process paths. Identify reversible processes. • Locate the unknowns in the balance equations and/or the property relationships. Solve for them....
