Design, Calibration and Implementation of a Biosynthetic Water Vapor Source

In efforts to generate a modeling and simulation system for the environmental control and life support system for a small plant growth chamber, the requirement for a biosynthetic water vapor source was found. The water vapor source was designed to inject a known and controlled rate of water vapor into the laboratory version of NASA Ames Research Center's Salad Machine. The rationale for a water vapor source, the design of the source device, the procedures and results of calibration and the method of integrating and utilizing the device with the Salad Machine are described.
