RP-1460- Design Specifications for Wet-Bulb Aspirator Apparatus PDF

The aim of this project is to be able to specify the design guidelines and considerations required to construct an aspirated psychrometer capable of measuring the wet-bulb temperature to within plus/minus 0.05°C. This is done by means of an analytical model used to predict the error in the measurement of the wet-bulb temperature over a range of conditions. Also to validate the model an aspirated psychrometer is built in accordance with the model and tested over a range of experimental test conditions. The analytical model and the experimental test apparatus are described in detail in this document.
