Laboratories Best Practices Energy Recovery Overview Energy recovery can substantially reduce the mechanical heating and cooling requirements associated with conditioning ventilation air in most laboratories. Laboratories typically require 100 outside air at high ventilation rates, between 6 and 15 air changes per hour, primarily for safety reasons. The heating and cooling energy needed to condition this air, as well as the fan energy  more...

Instrumentation and Control Temperature Pressure Flow Level and Position Indication Overview Instrumentation is the art of measuring the value of some plant parameters, for example, temperature, pressure, flow, or level to name a few, and supplying a signal that is proportional to the measured parameter. The output signals are standard signals and can then be processed by other equipment to provide indication, alarms or automatic control. This course covers five modules  more...

Characteristics and Properties of Metals The understanding of the structure and properties of metals, stress mechanisms, failure modes and the characteristics determine their usefulness for a specific application. Often, materials are subject to variable forces (loads). The mechanical engineer calculates these forces to establish the service that can be expected and material scientists experiment to determine how materials deform  more...

Engineering Symbology Prints and Drawings Drawing is the universal language of engineering. Drawings from an engineer provide a raw account of the fundamentals that will eventually go into making something useful and necessary. Engineering drawings are a formal and precise way of communicating information about the shape, size, features and precision of physical objects. The drawings of the engineer are an obvious case of making  more...
