What is the fracture toughness of a material? 17.7. “Fracture toughness” describes the resistance of brittle materials to the propagation of flaws under an applied stress, and it assumes that the longer the flaw, the lower is the stress needed to cause fracture. The ability of a flaw to cause fracture depends on the fracture […]
What is a quasi-equilibrium process?
What is a quasi-equilibrium process? In thermodynamics, a quasi-static process (also known as quasi-equilibrium, from the Latin quasi, meaning ‘as if’), is a thermodynamic process that happens slowly enough for the system to remain in internal equilibrium. Any reversible process is a quasi-static one. Why quasi static process is important? Equilibrium in a system in […]
On what factors the efficiency of Carnot engine depends?
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 […]
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 – […]
How do you calculate average speed in miles per minute?
How do you calculate average speed in miles per minute? The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2. How do you calculate speed with minutes? Speed Calculator Or, if you […]
