What is the input offset voltage of an op amp? The input offset voltage is defined as the voltage that must be applied between the two input terminals of the op amp to obtain zero volts at the output. Ideally the output of the op amp should be at zero volts when the inputs are […]
What is known as the efficiency of doing work?
What is known as the efficiency of doing work? By working efficiently, more can be produced with the same amount of input (resources)(1). In short, achieving more for lower costs, a higher return and less pressure. Efficiency means ‘doing things in the right way’. 2. Two sorts of efficiency are often referred to, namely static […]
What is the name of the procedure that scientists often follow to solve problems?
What is the name of the procedure that scientists often follow to solve problems? At the core of biology and other sciences lies a problem-solving approach called the scientific method. What process do scientist use as a way to perform research with defined steps that include experiments and careful observation? The scientific method is a […]
What is 2/4 shell-and-tube heat exchanger?
What is 2/4 shell-and-tube heat exchanger? Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fluid in the tubes passes through the fluid in the shell. Two and four pass designs are common because the fluid can enter and exit […]
What is rear view in drawing?
What is low temperature refrigeration?
What is low temperature refrigeration? Low temperature refrigeration is defined as those applications requiring evaporator temperatures in the range of -20 oF down to -250 oF. The vast majority of installations would be at temperature above -125 oF., however systems down to -250 oF are covered. What are the approximate temperature ranges for low medium […]
What is the main advantage of the ranch style home?
What is the main advantage of the ranch style home? Here are some of the advantages of a ranch-style home: Larger living space: The lack of staircases frees more square footage for living area. Easier access to the great outdoors: Ranch-style homes were developed with easy access to the yard in mind. What are the […]
What are the advantages of closed loop circuits over open loop circuits?
What are the advantages of closed loop circuits over open loop circuits? Closed-loop control systems have many advantages over open-loop systems. One advantage is the fact that the use of feedback makes the system response relatively insensitive to external disturbances and internal variations in system parameters such as temperature. What are the advantages of open […]
Why does deformation occur along plate boundaries?
Why does deformation occur along plate boundaries? Crustal Deformation Processes As the plates move, the crust deforms dominantly along the plate margins. Therefore, temperature and pressure control deformation processes. Ductile rocks tend to bend, fold, stretch, or flow due to compressional or extensional forces. Brittle rocks, on the other hand, tend to break. What force […]
How can I reduce my stress concentration?
How can I reduce my stress concentration? These include: Avoiding sharp corners and only using rounded corners with maximum radii. Sanding and polishing surfaces to remove any notches or defects that occur during forming and processing. Lowering the stiffness of straight load-bearing segments. Placing notches and threads in low-stress areas. How do you calculate stress […]
