What is the difference between displacement and true power factor?
'Displacement power factor' is the technically-correct term used to describe the cosine of the phase angle (i.e. the angle by which the load current leads or lags the supply voltage) due to the reactance of a load. Usually, when we talk about the 'power factor' of a load, we mean 'displacement power factor'.However, another type of power factor can exist in a circuit, due to the presence of harmonics in the current waveform, due to non-linear loads such as SCR rectifiers. This type of power factor is temed 'distortion power factor', and may be corrected using filters.So, the terms 'displacement' and 'distortion' are used whenever it is necessary to clarify these different types of power factor.
When a material is loaded within elastic limit the what is proportional to the what produced by the stress?
The displacement is proportional to the strain. This does not factor for creep and time.
Is it advisable to correct the power factor to unity?
power factor depends on the load being fed if the load is entirely resistive power factor will be unity ..if the load includes an inductor or capacitpr due to phase displacement between v and i the pf will be lag or lead respectievly
What is a non positive displacement compressor?
Well it is very important factor in fluid mechanics. The term comes often in compressors and Pumps. Displacement means change of place( Fluid ), Positive displacement means at all points of operating the discharge will be the same where as the discharge in non positive displacement varies at various operating points. For clear idea on the above compare the reciprocating pump with centrifugal pump at various operating points (by throttling) discharge valve).
Is it true that all hydraulic motor are positive displacement?
yes.only positive displacement pumps can be used in hydraulics

When displacement per unit time is tripled the velocity increases by what factor?
three times
What are the factor affecting on the simple pendulum?
The factors that affect a simple pendulum are; length; angular displacement; and mass of the bong.
When a material is loaded within elastic limit the what is proportional to the what produced by the stress?
The displacement is proportional to the strain. This does not factor for creep and time.
Why can age be a contributing factor in the formation of a bunion?
Age has also been noted as a factor in developing bunions, in part because the underlying bone displacement worsens over time unless corrective measures are taken.
Why is displacement of displacement?
The difference between the final and the initial position of an object is called displacement. Unit of displacement is metre . Displacement <= Distance always.
Whereas impulse involves the time that a force acts work involves what factor?
Work is the force multiplied by the displacement (the distance that the force moves an object).
How do you get displacement from a displacement graph?
To get displacement from a displacement graph, just look at the Y- axis for the particular time (displacement versus time). For the displacement graph, the Y-axis is usually displacement.
Is it advisable to correct the power factor to unity?
power factor depends on the load being fed if the load is entirely resistive power factor will be unity ..if the load includes an inductor or capacitpr due to phase displacement between v and i the pf will be lag or lead respectievly
What are 3 useful displacement reactions?
Two types of displacement reactions are known:- single displacement- double displacement
What is more accurate volume displacement or dimensions of an object?
Either can be accurate. Depends on how accurate your measurements or equipment is. The shape of the objects could be a major factor, too.
What is the result of adding a displacement vector to an another displacement vector?
another displacement
