Kp = 1 lb. of air at constant pressure 0.2378 × 772 = 183.5 = 100 Kv = 1 lb. of air at constant volume 0.1688 × 772 = 130.3 = 71 Difference, being heat converted into power 0.0690 × 772 = 53.2 = 29 Or, in a hot-air engine without regeneration, the maximum effect of 1 lb. of air heated 1° Fahr. would be 53.2 f.p.
The following were the data for a day of 24 hours, with an interval of half an hour: 8:55 P.M. one day to 8:55 P.M. the next, interval 8:30 to 9 A.M. Anthracite used, 18.4 cwt.; coke used, 3.42 cwt.; water used for steam injection, 217.3 gallons; water used in scrubber, 4,106 gallons; water used in cooling the cylinder, 20,000 gallons; oil used in cylinder, 14.84 pounds; grease, 1.8 pounds; revolutions of machine, 142,157, or 100.8 per minute; effective work, 75.86 French horse power, or 77.4 British; gas used, 6,742 cubic feet per hour, at 772 mm. pressure and 70.7° F., or 83.7 cubic feet per effective horse power; efficiency, 69 per cent.
The time when Coroebus ran his race, and thus furnished an era for all the subsequent chronologists and historians of his country, is generally regarded as about the year 776 before Christ; and the result of the calculations of Varro's astrologer, and of the astronomers who perfected it, was, that to lead such a life as Romulus led, a man must have been born at a time corresponding with the first year of the second Olympiad; that is, taking off from 776, four years, for the first Olympiad, the first year of the second Olympiad would be 772; this would make the time of his birth 772 before Christ; and then deducting eighteen years more, for the age of Romulus when he began to build his wall, we have 754 before Christ as the era of the foundation of Rome.
She was the first in the series of Charlemagne's wives, who, it is said, were nine in number. By the divorce he incurred the resentment of Desiderius, who required the Pope to anoint the sons of Carloman as kings of the Franks. In 772 Charlemagne crossed the Alps by the Mont Cenis and the St. Bernard, captured Pavia, and shut up Desiderius in a Frank monastery.
He visited Hadrian at Rome, renewed the Donation of Pepin, and concluded a pact of eternal friendship with the Papacy. Then followed the period of the Saxon wars, as much a crusade against German heathenism as the vindication of old and dubious claims to suzerainty. The first campaign against the Saxons had taken place in 772; their final submission was not made till 785.
These latter you have indeed reason to be proud of, for there are few finer. The increase of importation of sugar is striking. In Britain in 1856, our imports of this article were 6,813,000 lbs., in 1865 it was 7,112,772 lbs. Though all this did not come to Greenock, yet from what you do in this trade, I think the word holds good that we as Scotchmen are sweet-toothed.
Thus the amount of heat which will raise the temperature of a pound of water one degree of the thermometer, will, if expended, say in the expansion of steam, lift a weight of 772 pounds one foot, or a weight of one pound 772 feet: and the same exact quantity of heat can, by certain means, be recovered, through the expenditure of exactly that amount of mechanical motion.
If the average price remains at the figure for the period March 31, 1908, to September 15, 1909 viz. £287 a further sum of £22,673,000 may be required in excess of £84,099,818 already required under the Acts of 1903 and 1909; making £106,772,818. This total includes nearly £1,000,000 for re-sales to owners and some provision for evicted tenants.
With American countries the value of our exports has increased from $44,160,285 to $54,613,598, an increase of $10,453,313, or 23.67 per cent. The total increase in the value of exports to all the countries with which we have reciprocity agreements has been $20,772,621. This increase is chiefly in wheat, flour, meat, and dairy products and in manufactures of iron and steel and lumber.
It is recorded that the sympathy of the people was with the exiles. These things happened in the year 843. The Fujiwara sought a precedent in the action of their renowned ancestor, Momokawa, who, in 772, contrived the degradation and death of the Crown Prince Osabe on a charge of sorcery But Momokawa acted from motives of pure patriotism, whereas Yoshifusa worked in the Fujiwara interests only.
