Property tables list “enthalpy” ( h ) and “entropy” ( s ) in addition to p , T , v and u More about entropy later in the semester (2 nd Law) Enthalpy: a property defined for simplicity and convenience Total enthalpy: H = U + p V Specific enthalpy: h = u + pv Commonly used in open system analysis (control volume) 9/15/2010 2 ME200 Therm I Lecture 10, Prof. Mongia Enthalpy

Thermodynamic relationships sometimes complex; tables provide easy way of listing relevant properties and looking them up during analysis Property information available for compressed liquid, saturated liquid, liquid-vapor mixture, saturated vapor, and superheated vapor for many pure substances Tables A-1 through A-27 (SI units); Tables A-1E through A-25E (USCS units) very important to understand structure for efficient problem solving! 9/15/2010 3 ME200 Therm I Lecture 10, Prof. Mongia Property Tables
