This article provides a survey of some of the most popular combustion analyzers on the market. This review goes over some of the cheaper models, which are optimal for technicians, and more feature-rich models for engineers.
Exciting new technologies promise large improvements in the fuel efficiency of heavy trucks, which account for about 20 percent of traffic in the United States. This article reviews the technologies and explains how they work; it also assesses their viability.
The McLeod gauge is used to take pressure measurements of vacuum chambers and to calibrate other gauges. Its principle of operation relies on Boyle’s Law, and so assumes an ideal gas. This is fine for incompressible gases, but is a drawback in typical vacuum operations.
This article contains a brief history of the design of the Tesla turbine, which is a bladeless turbine invented by Nikola Tesla in 1908 to 1913. Materials limitations prevented the turbine from gaining mainstream acceptance then, but modern technology may make the Tesla turbine due for a comeback.
This article provides an engineering perspective on the best range of humidity for people, books, and electronics. Also discussed is how humidity is measured and the best ways to control indoor humidity.
