The Vapor Pressure of Dog's Blood at Body Temperature
نویسنده
چکیده
The vapor pressures of dog's blood and blood plasma were determined at 37.5 degrees by the dynamic method and the osmotic pressures calculated from the experimental data. The vapor pressures calculated from experimentally determined freezing point data agreed, within the experimental error, with the values obtained from direct measurement. The vapor pressure lowering produced by the colloid constituents of the blood was also determined and found to be minimal compared to that of the other constituents.

The Vapor Pressure of Dog's Blood at Body
An evaluation of the colligative properties of the blood is of paramount theoretical importance, for such properties enter as fundamental factors in all physicochemical considerations based either on the kinetic theory or on thermodynamics. Despite this importance, no direct measurements of the colligative properties of blood have been made at body temperature. 1 Our knowledge of these function...
متن کاملNumerical Study of Spherical Vapor Layer Growth Due to Contact of a Hot Object and Water
Vapor film formation and growth due to contact of a hot body and other liquids arise in some industrial applications including nuclear fuel rods, foundry and production of paper. The possibility of a steam explosion remains in most of these cases which could result in injuries and financial damage. Due to the importance of such phenomenon, this study deals with vapor layer forming, growth, and ...
متن کاملHistorical changes of temperature and vapor pressure deficit during the crop growing season in Iran
Climate change variables have rarely been analyzed specifically for the growing season of crops. In this study, changes in minimum (Tmin) and maximum temperature (Tmax), daily maximum saturated vapor pressure (VPsat) and estimated daily VPD weighted for transpiration (VPDtran) were examined at five locations in Iran over 40 years during the growing seasons of chickpea and maize. The results of ...
متن کاملPressure Dependence of Liquid Vapor Pressure: An Improved Gibbs Prediction
A new model for the vapor phase of a pressurized liquid called "the cluster model: which is originally introduced in this work, along with an accurate equation of state for the liquid phase called the LIR, is used to derive an accurate equation for the vapor pressure of liquid as a function of external pressure. The chemical Potential of both phase have been found to be in good agreement wi...
متن کاملPrediction of the Liquid Vapor Pressure Using the Artificial Neural Network-Group Contribution Method
In this paper, vapor pressure for pure compounds is estimated using the Artificial Neural Networks and a simple Group Contribution Method (ANN–GCM). For model comprehensiveness, materials were chosen from various families. Most of materials are from 12 families. Vapor pressure data of 100 compounds is used to train, validate and test the ANN-GCM model. Va...
