By ca-sing two conical surfaces of cast-iron immersed in mercury and contained in an iron vessel to rub against one another when pressed together by a lever, Joule obtained 776.045 foot-pounds for the mechanical equivalent of heat when the heavy weights were used, and 774.93 foot-pounds with the small driving weights.
The set of ten rods is thus equivalent to four sets of slips as described above, and by their means we may multiply every number less than II,irr, and also any number (consisting of course FIG.
When work is done against these forces no full equivalent of potential energy may be produced; this applies especially to frictional forces, for if the motion of the system be reversed the forces will be also reversed and will still oppose the motion.
In 1839 Seguin endeavoured to determine the mechanical equivalent of heat from the loss of heat suffered by steam in expanding, assuming that the whole of the heat so lost was consumed in doing external work against the pressure to which the steam was exposed.
A very convenient rule is to allow one brake horse-power of motor for every to foottons of work done at the hook; this is equivalent to an efficiency of 661%, and is well on the safe side.
By early writers the word was generally given as an equivalent of the Linnaean Loxia, but that genus has been found to include many forms not now placed in the same family.
Other authorities suggest that it is going much too far to deny the existence of religion altogether, and instance as proof of the divinity of the supra-normal anthropomorphic beings of the Baiame class, the fact that the Yuin and cognate tribes dance around the image of Daramulun (their equivalent of Baiame) and the medicine men " invocate his name."
P. Joule to achieve; his experiments conclusively prove that heat and energy are of the same nature, and that all other forms of energy can be transformed into an equivalent amount of heat.
The award of the court is thus the equivalent of the determination of a special board in Victoria, and deals with the same questions, the most important of which are the minimum rates of wages and the number of working hours per week.
Under this act the appropriation of these surplus funds to certain trust purposes in the Federal treasury is held to be equivalent to payment to the states.
All of them make use of Marconi's antenna in some form both at the transmitting and at the receiving end, all of them make use of an earth connexion, or its equivalent in the form of a balancing capacity or large surface having capacity with respect to the earth, which merely means that they insert a condenser of large capacity in the earth connexion.
The equivalent of the alb in the ancient Churches of the East is the sticharion (art bpeov) of the Orthodox Church (Armenian shapik, Syrian Kutina, Coptic stoicharion or tuniah).
Praetor ius's Cammerton, or chamber pitch, formulated in his diagrams for voices and instruments, is, he says, a whole tone higher; equivalent, therefore, to a' 475.65.
In Argentina these burdens bear heavily upon the labouring classes, and in years of depression they send away by thousands immigrants unable to meet the high costs of living, For the year 1900 the total expenditures of the national government, 14 provincial governments, and 16 principal cities, were estimated to have been $208,811,925 paper, which is equivalent to $91,877,247 gold, or (at $5.04 per pound stg.) to £18,229,612, ios.
In the month of June 1880, President Avellaneda and his ministers left Buenos Aires, and this act was considered by the porteno leaders equivalent to a declaration of war.
One of the first who took in hand the determination of the mechanical equivalent of heat was Marc. Seguin, a nephew of J.
The net effective work of lifting that can be performed by a man turning a handle may be taken, for intermittent work, as being on an average about 5000 foot-lb per minute; this is equivalent to 1 ton lifted about 24 ft.
The electromotive force of the coil is, however, great enough to create in these air gaps displacement currents which are of magnitude sufficient to be equivalent to the conduction current required to actuate a telephone.
IDUMAEA ('160v saia), the Greek equivalent of Edom (aip), a territory which, in the works of the Biblical writers, is considered to lie S.E.
The pastoral and agricultural industries have been hampered by fluctuations in the value of the currency, farm products being sold at a gold value for the equivalent in paper, while labourers are paid in currency.
In ordinary banks the deposits amounted to £106,625,000, so that the total deposits stood at £143,830,000, equivalent to the very large sum of £34, 18s.
Assuming that the whole of the energy was converted into heat, when the air was subjected to a pressure of 21.5 atmospheres Joule obtained for the mechanical equivalent of heat about 824.8 foot-pounds, and when a pressure of only 10 .
Is equivalent to an amount of heat sufficient to raise nearly 6 gallons of water from 60° F.
But in other cases the encrusted star settles in that portion of the revolving vortex which has a velocity equivalent to its own, and so continues to revolve in the vortex, wrapped in its own firmament.
To know the mind of the god was equivalent to knowing what the god in question proposed to do.
From these experiments Joule obtained 72.692 foot-pounds in the latitude of Manchester as equivalent to the amount of heat required to raise i lb of water through 1° Fahr, from the freezing point.
Joule inferred from them that the mechanical equivalent of heat is probably about 772 foot-pounds, or, employing the centigrade scale, about 1390 foot-pounds.
He also determined a roughly approximate value for the mechanical equivalent of heat from the results of these experiments.
If she had no children, he returned her the dowry and paid her a sum equivalent to the bride-price, or a mina of silver, if there had been none.
In diameter, to a total resistance of zoo ohms. The actual current required to work the instrument is 3.3 milliamperes (equivalent approximately to the current given by 1 Daniell cell through 3300 ohms), but in practice a current of to milliamperes is allowed.
The indicator was connected with a Ruhmkorff coil or other equivalent apparatus, designed to cause a continual succession of sparks to pass between the indicator and a metal plate situated beneath it and having a plane surface parallel to its line of motion.
