Footnote 4: Where range of temperature is given, coefficient is mean over range.
Numerous values have been given for this coefficient of friction, f, which, from experiment, apparently varies with both the diameter of pipe and the velocity of the passing steam.
Mass has two aspects: it is at the same time a coefficient of inertia and an attracting mass entering as factor into Newtonian attraction.
The acceleration of a moving point has the same direction as the resultant of all the forces to which it is subjected; it is equal to the quotient of this resultant by a coefficient called mass of the moving point.
On the other hand, if the coefficient of attraction depends upon the velocity, since the velocities of two bodies which mutually attract are not in general the same, how will this coefficient depend upon these two velocities?
We should therefore distinguish the mass coefficient of inertia and the mass coefficient of attraction.
We might interpret this result by supposing that thecoefficient of gravitation is not the same in the three cases.
I shall further suppose that, in this world, all bodies have the same coefficientof dilatation, so that the length of any rule is proportional to its absolute temperature.
If the coefficient of inertia is not constant, can the attracting mass be?
The difference in the value of the coefficient in the two cases is perhaps due to errors of experiment.

The assumption that the coefficient of contraction cc is constant for different values of [rho] is probably only true when [rho] is not very large.
Darcy and Bazin's experiments alone were conclusive as to the dependence of the coefficient c on the dimensions of the channel and on its roughness of surface.
The coefficient of discharge, which for practical purposes is the most important of the three coefficients, is best determined by tank measurement of the flow from the given orifice in a suitable time.
Experiments made by a whirling machine, in which the plate is fixed on a long arm and moved circularly, gave the following values of the coefficient f.
The most that can be done is to limit the choice of the coefficient for a pipe within certain comparatively narrow limits.

The temperature coefficient is, however, higher than for platinum silver (0.
In the majority of instances in which quartz threads are applied in the laboratory, it is desirable to keep the coefficient of torsion as small as possible, and hence threads are used as fine as possible.
The temperature coefficient of this constant was too small for M.
The specific resistance will be seen to be about one and a half times greater than that of German silver, and the temperature coefficient is about 0.
Its recommendation as a standard depends on its chemical inertness, its small temperature coefficient (0.

The piece should not be quite dry and the coefficient of expansion between the two clays as near alike as possible.
If the coefficient of expansion of these three layers differs, in other words, if the glaze does not fit, the result is crazing, that bugbear of the potter.
The maximum of marks allotted for each subject is twenty, and the number of marks gained by each candidate is multiplied by a coefficient fixed according to the relative importance of the subject.
In fact, the coefficient of decrease of utility is greater than the coefficient of increase of the stock of goods.
Thus Sylvester finds for the coefficient of x^n in 1 1 - x.
The enumeration is given by the coefficientof x^n.
The fifth set of experiments was made upon the Red Rover, City of Canterbury, Herne, Queen, and Prince of Wales, and in the case of those vessels the coefficient rose to 2550.
The purpose of the experiments was to establish a coefficient of performance, which with any given class of vessel would enable the speed, which would be obtained with any given power, to be readily predicted.
The coefficient of performance of the Fairy is 464.
Dybskowsky found that putting the coefficient of solubility of phosphine in pure water at .
This is done by inserting a small shunt y, parallel with the coil fl, and thus the temperature coefficient of fl and fr are made absolutely equal.
The mean velocity past the central vertical was recommended for use, as not being affected by wind; the reduction coefficientcould at present only be found by special experiment for each site.
The elevation of the coefficient is prima facie evidence the obesity is due to excess of assimilation, while depression of the coefficient indicates default of assimilation.
When the urea is stationary, which is most frequently the case, it is necessary to calculate the coefficient of oxidation; that is, the relation existing between the solid matters of the urine and the urea.
The coefficient of friction will be thereby reduced; slipping will ensue, and the transmission may cease either in whole or in part.
This result points to a temperature coefficient of about 1.
It is suggested by Delf that this low coefficient of destruction is opposed to the enzyme or protein-like theory of the nature of the vitamine, and suggests a simpler constitution.
By steeping and drying a very steely Scottish barley, the coefficientof mealiness was raised from 29.
Brown and his co-workers determine the coefficient of mealiness of a barley as follows: Five hundred corns are cut transversely in a corn cutter and the percentage of mealy, half mealy and steely corns is noted.
Further, by suitably choosing the positions of the deflectors and the coefficient of torsion of the fibre, it is possible to make the temperature coefficient vanish.
If the percentage of each class be multiplied by its special value, and the sum of the products divided by 100, the result is the coefficient of mealiness.
In effect we have, in the coefficient of correlation, nothing more than a refinement of the method of comparing two curves on a graph.
It is to be a coefficient with the objective values of goods in determining prices.
It is a causal coefficient with the absolute value, similarly explained, of the bushel of corn, in explaining the wheat-price of corn.
This coefficient has been used enough by economists not to require detailed explanation here.
The coefficient of correlation condenses the information to such a degree as to make comparison easy.
Finally, Professor Taussig recognizes a coefficient with the quantity of specie in the temper of the business community.
The curves tell the story, in a general way, whereas the coefficient of correlation sums up all the comcomitant variations (and disagreements) in one figure.
When the probable error is low, and the coefficientof correlation high (as .
In a recent study an attempt has been made to measure the coefficient of correlation between cousins.
In athletic power the coefficient was still higher, .
However it is very evident that the coefficient of attraction is at its maximum between first cousins, and probably there are actually more marriages between first cousins than between those of any other recognized degree of consanguinity.
It will be recalled that the coefficient of correlation measures the resemblance between two variables on a scale between 0 and-1 or +1.

In an ordinary population it has been found that the age at death of brothers and sisters furnishes a coefficient of correlation of the order of .
As we show in more detail in Chapter IV, it was found, no matter what physical or mental trait was measured, that the coefficient of correlation between parent and child was a little less than .
In this case, the mathematician can give us a coefficient of resemblance, or of assortative mating, which we write as zero.
This is the coefficient for most physical and mental characters: it is the coefficient for such pathological traits as deafness and insanity, which are obviously due in most cases to inheritance rather than infection.
A zero coefficient here would show that there is no association; that from the age at which one dies, nothing whatever can be predicted as to the age at which the others will die.
If on the other hand (as is indeed the popular idea) a tall man tended to marry a woman who was shorter than the average, the coefficient of correlation would be less than 0; it would have some negative value.
For the inheritance of physical and mental characters, in general, the coefficient would be about .
In fact, the coefficient of correlation is nothing more than a measure of the regression, and it is probably simpler to think of it as correlation than it is to speak of a Law of Regression, as Sir Francis did.
