On what factors the efficiency of Carnot engine depends? efficiency of the Carnot engine depends on the temperature of the hot and cold reservoirs . Which is more effective way to increase the efficiency of a Carnot engine? Hence efficiency of carnot engine can be increased by a greater amount by increasing the temp. What […]
What is human-computer interaction and why is it important?
What is human-computer interaction and why is it important? Human-computer interaction (HCI) is a multidisciplinary subject that focuses on computer design and user experience. It brings together expertise from computer science, cognitive psychology, behavioural science, and design to understand and facilitate better interactions between users and machines. How human-computer interaction affects the society today? The […]

What is conjugate depth in hydraulic jump?
What is conjugate depth in hydraulic jump? In fluid dynamics, the conjugate depths refer to the depth (y1) upstream and the depth (y2) downstream of the hydraulic jump whose momentum fluxes are equal for a given discharge (volume flux) q. The depth upstream of a hydraulic jump is always supercritical. Why momentum equation is used […]
What process results in an increase of entropy?
What process results in an increase of entropy? Increasing the number of molecules in a system also increases the number of microstates, as now there are more possible arrangements of the molecules. Therefore, any change that results in a higher temperature, more molecules, or a larger volume yields an increase in entropy. What are the […]

Terms in this set (7) secure the scene. separate the witnesses. scan the scene. seeing the scene (taking photographs) sketch the scene. search for evidence. secure the collected evidence. What are the six phases of the forensic investigation process? There are following six […]
What happened to farmers in the 1930s?
What happened to farmers in the 1930s? When prices fell they tried to produce even more to pay their debts, taxes and living expenses. In the early 1930s prices dropped so low that many farmers went bankrupt and lost their farms. Some farmers became angry and wanted the government to step in to keep farm […]
Why seismic survey method is widely used in oil and gas exploration?
Why seismic survey method is widely used in oil and gas exploration? Seismic survey is a method used during the exploration phase of oil and gas development. The method gives a first idea of what is present underneath the earth’s surface. The reflected and refracted seismic waves are recorded by a receiver (geophone or hydrophones […]
Has anyone ever died from turbulence?
Has anyone ever died from turbulence? Each year, approximately 58 people in the United States are injured by turbulence while not wearing their seat belts. From 1980 through June 2004, U.S. air carriers had 198 turbulence accidents*, resulting in 266 serious injuries and three fatalities. Can a plane be brought down by turbulence? TLDR – […]
Why is 0.2% proof stress used?
Why is 0.2% proof stress used? In other words, proof stress is the point at which a particular degree of permanent deformation occurs in a test sample. Proof stress is also called offset yield stress. Typically, the stress needed to produce 0.2 percent of plastic deformation is considered proof stress. How the 0.2% offset yield […]
