Does ideal vapor compression refrigeration cycle involve any internal irreversibility? The ideal compression refrigeration cycle is not an internally reversible cycle, since it involves throttling which is an irreversible process. What are the main components of Vapour compression refrigeration system? 3.4. 2 Vapor compression refrigerators. A detailed description of the vapor compression refrigeration is available […]

What is the purpose of liquid limit test?
What is the purpose of liquid limit test? Value of liquid limit is used to classify fine grained soil. It gives us information regarding the state of consistency of soil on site. Liquid limit of soil can be used to predict the consolidation properties of soil while calculating allowable bearing capacity & settlement of foundation. […]
Why is insulation important in homes?
Why is insulation important in homes? Heat naturally flows from warmer areas to cooler areas. Insulation helps resist this airflow through walls, ceilings, roofs, and other surfaces of the home. It stops heat from exiting the house in the winter and entering the house in the summer, acting as a protective barrier between you and […]
What is separation of components of air?
What is separation of components of air? From Wikipedia, the free encyclopedia. An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is fractional distillation. How is oxygen separated from air? About 78 per […]

How is safety factor calculated?
How is safety factor calculated? A very basic equation to calculate FoS is to divide the ultimate (or maximum) stress by the typical (or working) stress. A FoS of 1 means that a structure or component will fail exactly when it reaches the design load, and cannot support any additional load. How is safety factor […]
What is calibration of pressure gauge?
What is calibration of pressure gauge? Basic pressure gauge calibration is the comparison of measurement values of a unit under test (your gauge) with those of a more accurate calibrated reference instrument. The purpose of calibration is to maintain the quality and accuracy of measurement and to ensure the proper working of a particular instrument. […]

How do you find the maximum theoretical specific gravity?
How do you find the maximum theoretical specific gravity? Theoretical maximum specific gravity is determined by taking a sample of loose HMA (i.e., not compacted), weighing it and then determining its volume by calculating the volume of water it displaces (Figure 1). Theoretical maximum specific gravity is then the sample weight divided by its volume. […]
