How is hose size measured? Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter. As a matter of fact, that is how the hoses and tubes are differentiated. Dash numbers, the industry standard, are typically used to describe hose and coupling size. Is hose diameter internal or external? Both Hozelock […]
How does annealing temperature affect PCR?
How does annealing temperature affect PCR? The annealing temperature (Ta) chosen for PCR relies directly on length and composition of the primers. This can lead to nonspecific PCR amplification and will consequently reduce the yield of the desired product. What will happen during the PCR if the annealing temperature is too low? If temperature is […]
How does Reynolds number effect the flow of fluid?
How does Reynolds number effect the flow of fluid? laminar flow occurs at low Reynolds numbers, where viscous forces are dominant, and is characterized by smooth, constant fluid motion; turbulent flow occurs at high Reynolds numbers and is dominated by inertial forces, which tend to produce chaotic eddies, vortices and other flow instabilities. What does […]
Who plays more fortnite or Apex?
Who plays more fortnite or Apex? Apex Legends simply cannot compete with that. The most recent landmark announced from EA came in October 2019, when it revealed that 70 million people had downloaded Apex. It only managed to secure more PS4 downloads than Fortnite in 2019 because so many people had already downloaded Fortnite before […]
What is a second order system?
What is a second order system? 3.6. 8 Second-Order System The second-order system is the lowest-order system capable of an oscillatory response to a step input. If both roots are real-valued, the second-order system behaves like a chain of two first-order systems, and the step response has two exponential components. What is the time constant […]
Can entropy be created or destroyed?
Can entropy be created or destroyed? Entropy is not a conserved quantity. It can be created. In every irreversible cyclic process it gets created. However, entropy cannot be destroyed. Is it true that matter can neither be created nor destroyed? The Law of Conservation of Mass The same amount of matter exists before and after […]
What is a major distinction between the filter theory and the late selection theory?
What is a major distinction between the filter theory and the late selection theory? What is a major distinction between the filter theory and the late-selection theory? Filter theory assumes a limited channel capacity, while late selection assumes that any capacity limits must come later in processing. When Stevens and Coupe presented congruent or incongruent […]
Does increasing compression ratio increase power?
Does increasing compression ratio increase power? This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached with less fuel, while giving a longer expansion cycle, creating more mechanical power output and lowering the exhaust temperature. How does compression ratio affect power? The generally accepted […]
What is rake angle how it affects the formation of chips?
What is rake angle how it affects the formation of chips? Make the tool more sharp and pointed. This reduces the strength of the tool, as the small included angle in the tip may cause it to chip away. Reduce cutting forces and power requirements. Helps in the formation of continuous chips in ductile materials. […]
What is black box method?
What is black box method? Black box testing involves testing a system with no prior knowledge of its internal workings. A tester provides an input, and observes the output generated by the system under test. Black box testing is a powerful testing technique because it exercises a system end-to-end. What are the black box testing […]
