Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures. There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...

Source: Robert M. Rioux, Ajay Sathe & Zhifeng Chen, Pennsylvania State University, University Park, PA Vacuum is required for a number of laboratory procedures. This is most routinely achieved in the laboratory by the use of vacuum pumps. In addition to working at low pressures, vacuum pumps can also be used to enable rapid changing of the atmospheres in a reactor or flask by evacuation and backfilling.

Source: Laboratory of Dr. Dana Lashley - College of William and Mary Demonstrated by: Timothy Beck and Lucas Arney Many reactions in organic chemistry are moisture-sensitive and must be carried out under careful exclusion of water. In these cases the reagents have a high affinity to react with water from the atmosphere and if left exposed the desired reaction will not take place or give poor yields, because the reactants are chemically altered. In order to prevent undesired reactions with H2O...

Leveling Equipment

As leveling involves measuring vertical distances relative to a horizontal line of sight, it requires a graduated rod, called a level rod, for vertical measurements and an instrument called a level for a horizontal sight line. A level includes a high-powered telescope with a mechanism for leveling to ensure the line of sight is horizontal when the bubble in the spirit level is centered. Leveling rods, made of wood, metal, or fiberglass, are graduated in feet or meters and commonly used in two-...

FAQs
Engineers evaluate material properties, structural design, and operating conditions together because each affects how equipment responds to applied loads. The assessment may consider mechanical stress, temperature, pressure, vibration, corrosion, or electrical fault conditions. Reviewing these factors helps identify the governing limitation and ensures that the equipment remains within safe and reliable operating boundaries.
Applied stresses are compared with allowable limits rather than judged in isolation. Engineers also apply appropriate safety factors to provide additional margin for uncertainty, variations in operating conditions, and potential deterioration. This comparison supports design verification and equipment selection by showing whether expected loads remain acceptably below the levels associated with unsafe operation or failure.
Different loads can produce different failure modes, including deformation, insulation breakdown, fatigue, or catastrophic failure. Mechanical and thermal conditions may challenge structural performance, while electrical fault conditions can threaten insulation. Considering the relevant failure modes prevents an assessment from overlooking a critical weakness and helps align the evaluation with the equipment’s actual service environment.
The selected conditions depend on the equipment and its intended operation. An assessment may include static and dynamic loads, pressure, temperature, vibration, corrosion, and electrical fault conditions. These categories address both ordinary service demands and potentially severe events, allowing engineers to evaluate whether the equipment can continue operating safely under the conditions most relevant to its application.
Engineers first identify the equipment’s materials, structural design, operating conditions, and relevant load or fault scenarios. They then evaluate the resulting stresses and potential failure modes, compare those stresses with allowable limits, and apply appropriate safety factors. The conclusions can support design verification, equipment selection, maintenance planning, or decisions about compliance with safety requirements.
The assessment is useful whenever engineers must determine whether equipment is suitable for expected service conditions or whether a design satisfies its intended requirements. Comparing expected loads with allowable limits provides evidence for selecting equipment and verifying designs. It also helps reveal risks such as excessive deformation, insulation breakdown, fatigue, or other unsafe outcomes before service.
Capacity information connects equipment performance limits with ongoing engineering decisions. Maintenance planning can use the assessed limits and relevant failure modes to focus attention on conditions that may reduce reliable operation, including corrosion, vibration, temperature, or electrical faults. The same evaluation provides technical support for demonstrating that equipment meets applicable safety requirements and remains suitable for service.
