PSI is the amount of force that an air compressor can deliver 100 PSI, for example, equates to 100 pounds of force exerted per square inch. PSI is the measure of force that’s applied to a defined area, and determines the compressor’s ability to perform a specified amount...
Air resistance is usually calculated using the “drag equation”, which determines the force experienced by an object moving through a fluid or gas at relatively large velocity. This can be expressed mathematically as: In this equation,FDrepresents the drag force,pis the density of the fluid,vis...

Different air compressors are rated for different air compressor duty cycles. This determines the amount of time that the compressor can run-make air-out of a total cycle. The duty cycle is expressed as a percentage. The higher the duty cycle rating, the more time the compressor can spend ...

Ultimately, the type of application determines the choice between analog and digital displays. ASME directives 40.1 and 40.7 provide detailed guidance on the use of these display types in pressure gauges.ConclusionA pressure gauge is a method for measuring fluid, gas, water, or steam intensity in...

Question: What determines the failure mode (buckling or yielding) of a column? Columns: Columns are structural members used to carry axial compressive loads. For example, columns carry and transmit the loads from the ceiling to the foundation of a building. There are two types of colu...
