What does a tensile test determine? A tensile test applies tensile (pulling) force to a material and measures the specimen’s response to the stress. By doing this, tensile tests determine how strong a material is and how much it can elongate. What is the relationship between tensile strength and elongation? The force at material rupture […]
What is the use of reheat cycle in steam turbine?
What is the use of reheat cycle in steam turbine? The purpose of a reheating cycle is to remove the moisture carried by the steam at the final stages of the expansion process. In this variation, two turbines work in series. Why Carnot cycle is practically not possible? This means that the Carnot cycle is […]
Which element forms a protective coating when it rusts?
Which element forms a protective coating when it rusts? chromium How is filiform corrosion treated? This type of filiform corrosion can damage all types of aluminum products such as wheels, automobile bodies and aircrafts. To repair the effect requires sanding and the application of a new layer of coating. To prevent filiform corrosion, proper surface […]
Which metal is used for galvanizing?
Which metal is used for galvanizing? zinc coating What is the process of galvanizing steel? Hot dip galvanizing is the process of coating iron or steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). Galvanizing is probably the most […]
What does a comparator circuit do?
What does a comparator circuit do? A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some […]
What are the types of degradation?
What are the types of degradation? Introduction Types of soil degradation. Soil degradation can be classified into four main types of degradation: water erosion, wind erosion, chemical deterioration and physical deterioration. Water erosion. Wind erosion. Chemical deterioration. Physical deterioration. Human causes of erosion. Control of erosion. Conclusion. What are the 2 reasons for land degradation? […]
How do you calculate heat load of shell and tube heat exchanger?
How do you control the speed of a linear actuator?
What are the types of valves?
What are the types of valves? Common types of valves include: Ball Valve. Predominantly equipped with quick-acting 90-degree turn handles, these valves use a ball to control flow to provide easy on-off control. Butterfly Valve. Check Valve. Gate Valve. Knife Gate Valve. Globe Valve. Needle Valve. Pinch Valve. What are the three types of valve […]
