Excerpt from Notes on Heating and Ventilation
Heat is a form of motion. The modern scientific concep tion of heat is that it is produced by the motion of the particles of matter which compose any body. All matter is conceived as Heat. Being made up of small particles called molecules. These particles do not exist in a state of rest, but are in constant vibration. If these particles move slowly the body is at a low temperature; if they move more rapidly the body is at a higher temperature, the temperature of the body being determined by the rapidity of the motion of the particles. In measuring heat there are two properties to be considered - the intensity and the quantity. This may be compared to measuring water in a pipe. We measure the pressure of the water in the pipe by means of a gauge in pounds per square inch. The quantity of water is measured in pounds. In the same way the intensity of heat is measured by the thermometer in degrees and the quantity of heat is measured by com parison with the quantity of heat which a pound of water will absorb.

Paperback. Condition: New. Print on Demand. This book is a detailed analysis of various heating and ventilation systems commonly used in buildings. These range from simple direct steam heating to advanced central heating systems. The author clarifies how to achieve optimum comfort and efficiency. The book discusses how heat is lost from buildings through various means - direct transmission, air flow, and filtration - and provides detailed formulas for calculating heat loss in different constructions. The author also covers the basics of heat transfer, including conduction, convection, and radiation. The book draws heavily from experiments done under the supervision of Prof. M. E. Cooley, Dean of the Department of Engineering at the University of Michigan, and includes diagrams of tunnel sections designed by Prof. Cooley to improve central heating systems. The book is an excellent resource for steam fitters and designers of heating systems. 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. Seller Inventory # 9780282590055_0
