Fundamentals of Thermodynamics - Laboratory
Properties of Pure Substances - Saturation Pressure and Temperature of Water
Objectives
This laboratory will examine the pressure-temperature relationship of a pure substance (H2O) during liquid-to-vapour phase equilibrium, which is known as the saturation state or "boiling point'. The measured properties are compared to the published thermodynamics data (Steam Table values), with the aims of promoting understanding of pure substance behaviour and calculation of properties, and of identifying factors which differentiate calculated (theoretical) results from measured (experimental) results. The experimental set up will also allow the determination of vapour dryness fraction via a throttling calorimeter.
Results and Discussion
Provide suitable tabulations with units illustrating all readings taken, resistance correction applied, computed temperatures, temperatures from the Steam Table and the atmospheric pressure. Discuss differences observed in measured steam temperatures and those obtained from the Steam Tables. Outline possible measurement errors and precautions to overcome them. Show your complete calculation for obtaining the dryness fraction, including diagrams as noted over the page. [It is important that the units are always given whenever property values are quoted or computed].
