What are the applications of spreading coefficient?
The spreading coefficient is often applied in the field of pharmacy. Film coats are spread over tablets and lotions with mineral oils are spread on skin using surfactants. The spreading coefficient is the difference between the work of adhesion and the work of cohesion.
What is coefficient of friction between water and PVC tube?
the coefficient of the tube change due to submergence
Why the coefficient of volume expansion of the water different with coefficient of volume expansion of the ethanol?
Since there is extensive hydrogen bonding in case of water (two -OH per molecule) unlike ethanol (which has one -OH per molecule) so the intermolecular force difference is there between water and ethanol. Thus the coefficient of volumetric expansion will also be different, 'coz intermolecular force is a direct variable effecting this coefficient......
How does efficiency depend on mass and why is it like that?
There's no direct connection between efficiency and mass.
What is the function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
What is difference between efficiency and performance?
Efficiency is like a ratio. The higher the efficiency the less you have to put in or the more you get out. Performance is just how fast or how much it can make of something. Example: A hybrid car has a high efficiency because you get more mileage than say a muscle car, but the muscle car has higher performance because it goes faster and has more power.
What is the Meaning of management efficiency and effectiveness?
Between efficiency and effectiveness which one is more important for performance
What is the difference between allocative and technical efficiency?
no difference
What is the difference between factors and coefficient?
The difference between factors and coefficient is very distinct. A factor is a quantity which is multiplied with another to give a particular number as the result. A coefficient on the other hand is a multiplier that measures property.
What is difference between effectiveness and efficiency and why?
effectiveness refers to the ability to produce the desired results. efficiency refers to the correctness of the produced result ex; effectiveness is like making an engine of high performance and efficiency is like the extent to which it works and reach the goal of the manufacture
What is the difference between a subscript and a coefficient in a chemical formula?
The subscripts tell you how the atoms are bound together. The coefficient tells you how many atoms there are.
What is difference between high pressure liquid chromatography and high performance lequid chromatography?
there is no difference between high pressure and performance chromatography
Difference between technical efficiency and economic efficiency?
technical efficiency is related to change in output due to change in input and economic efficiency refers to a number of related concepts.
What is the difference between a coefficient and variable?
A variable is a part of a term which can change. A coefficient is a numerical constant, associated with a variable. For example, in the term 3x^2 , 3 is the coefficient, while x is a variable.
What is the difference between display and performance?
display is something you see, however, performance is something you do.
What is performance gaps?
Performance gap is the difference between current situation and intended situation.
Difference between objectives and performance targets?
Objectives exist on the strategic level. Market share, force reduction, production efficiency, etc. Performance targets on the tactical level. Percentage gain, additional savings, average service call cost reduction, etc.
