What is the basic principle of homogeneity of dimensions? Principle of Homogeneity states that dimensions of each of the terms of a dimensional equation on both sides should be the same. This principle is helpful because it helps us convert the units from one form to another. What is dimensional homogeneous? As said in the […]
What is patent and its importance?
What is patent and its importance? A patent is an exclusive form of Intellectual Property (IP) that provides the owners with the right to exclude or restrict others from exploiting the patented innovation or technology, which includes manufacturing, using, distributing, selling, or merchandising the patent invention. What is a design patent used for? A US […]
What is the coefficient of performance of the refrigerator?
What is the coefficient of performance of the refrigerator? The coefficient of performance, COP, of a refrigerator is defined as the heat removed from the cold reservoir Qcold, (i.e. inside a refrigerator) divided by the work W done to remove the heat (i.e. the work done by the compressor). How do you calculate the cooling […]
What are the 4 parts of a screw?
What is very important to remember when using a centrifuge?
What is very important to remember when using a centrifuge? If the liquid has a higher or lower density than water, you must balance the tubes by mass, not volume. The total mass of each tube should be as close as possible – this becomes increasingly important at very high rotor speeds. Running a centrifuge […]
What happens when TCC solenoid goes bad?
What happens when TCC solenoid goes bad? The main symptom of a TCC solenoid failure is the converter is not locking up. When the converter is not locking up you will notice the engine’s RPMs staying higher under load at highway speeds. Another symptom of a failed TCC solenoid is a fault code. How do […]
What is undercooling in refrigeration?
What is undercooling in refrigeration? The term subcooling (also called undercooling) refers to a liquid existing at a temperature below its normal boiling point. Normally, a refrigeration system has a subcooling stage, allowing technicians to be certain that the quality, in which the refrigerant reaches the next step on the cycle, is the desired one. […]
What is optimization query optimization methods?
What is optimization query optimization methods? Query optimization is the overall process of choosing the most efficient means of executing a SQL statement. SQL is a nonprocedural language, so the optimizer is free to merge, reorganize, and process in any order. The database optimizes each SQL statement based on statistics collected about the accessed data. […]
What is fluid power technology?
What is fluid power technology? Fluid power is the technology of generating, controlling, and applying smooth, effective power of pumped or compressed fluid, either a liquid (hydraulics) or air (pneumatics) to push, pull, rotate, regulate, or drive virtually all of the mechanisms of modern industry. How is power transmitted in fluid power? Hydraulic power, also […]
How do you turn an uncontrolled intersection?
How do you turn an uncontrolled intersection? At an intersection without STOP or YIELD signs (uncontrolled intersection), slow down and prepare to stop. Yield to vehicles already in the intersection or entering it in front of you. Always yield to the car that arrived first. Who gives way at an uncontrolled intersection? At an uncontrolled […]
