What is evaporating temperature in refrigeration?

What is evaporating temperature in refrigeration? As its name implies, refrigerant in the evaporator “evaporates”. Upon entering the evaporator, the liquid refrigerant’s temperature is between 40° and 50°F; and without changing its temperature; it absorbs heat as it changes state from a liquid to a vapor. What controls the flow of refrigerant to the evaporator? […]

Is Unix a time-sharing operating system?

Is Unix a time-sharing operating system? IIX is a multi-processing and multi-user timesharing operating system. UNIX provides a great range of programs and services that have made the UNIX system environment popular among users. What is a UNIX based operating system? What is UNIX? UNIX is an operating system which was first developed in the […]

What is ceramic backing in welding?

What is ceramic backing in welding? Ceramic backing strips can be used with every weldable material to reduce oxidation and prevent hydrogen inclusion, by providing a heat-reflecting, weld-supporting surface against which to deposit the welding consumable. Gas release gaps reduce porosity by preventing gas-entrapment. Why backing strip is used in welding? A backing (strip) is […]

What is the example of fusion welding?

What is the example of fusion welding? Examples of fusion welding processes Such processes where heat is applied by means of electric arc are termed as arc welding process. Similarly, all gas welding processes, resistant welding processes, and intense energy welding processes are basically examples of fusion welding. What is advanced welding? Course Description: Advanced […]

How do you derive the deflection of a beam?

How do you derive the deflection of a beam? Assuming that the deflection of the beam is sufficiently small, we can neglect the first derivative y′. Then the differential equation of the elastic line can be written as follows: y′′=M(x)EIord2ydx2=M(x)EI. The bending moment M(x) can be expressed in terms of the known external load q(x) […]
