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? […]

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 […]
How did the engineers solve the problem?
How did the engineers solve the problem? Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work. How can we […]
How do you calculate Q flow rate?

What is the power consumption of a light bulb?
What is the power consumption of a light bulb? 60 watts How do you determine the power rating of a light bulb? To find the kilowatt-hours your light bulb consumes per month, multiply the kilowatt use by the number of hours it’s on each month. Example 1: The incandescent bulb uses 0.06 kW of power […]
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 […]
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) […]
