Paperback. Etat : New. Print on Demand. This book compiles vapor pressure measurements of various compounds at low temperatures to support the author's work in separating natural gas mixtures and illuminating gas by fractional distillation. The author presents equations and curves for calculating vapor pressure based on temperature for each compound tested along with methods for calibrating thermometers and calculating heat of evaporation. The book discusses the significance of vapor pressure in separating gas mixtures and provides insights into the properties of various compounds at low temperatures, which can aid in understanding their behavior and potential applications in fields such as natural gas processing and cryogenics. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Etat : New. Print on Demand. This book presents a rigorous investigation of the changes in air composition that occur when atmospheric air enters coal mines. The author, an expert in the field, draws on extensive research and analysis to illuminate the processes that lead to the formation of black damp, a potentially hazardous accumulation of carbon dioxide and nitrogen. By comparing the composition of atmospheric air with that of mine air, the book reveals the complex interplay of factors that influence oxygen depletion and carbon dioxide enrichment, including the velocity of air currents, the extent of coal workings, and the presence of methane. This foundational knowledge is crucial for understanding the physiological effects of black damp on miners, its impact on the combustion of oil and acetylene lamps, and its role in the explosibility of methane-air mixtures. By contextualizing these insights within the broader history of mine safety and ventilation, this book provides invaluable guidance for improving air quality in underground environments and mitigating the risks associated with black damp.
