While these assets upgraded our efficiency, the LeBlanc house continued to be inadequate.
Great improvements, however, have been effected in the design of open fireplaces, and many ingenious contrivances of this nature are now in the market which combine efficiency of heating with economy of fuel.
There are also directors of stores, of naval construction, of the medical service, and of the submarine defences (which are concerned with torpedoes, mines and torpedo-boats), as well as of naval ordnance and works, The prefect directs the operations of the arsenal, and is responsible for its efficiency and for that of the ships which are there in reserve.
We have seen that the efficiency of an electromagnetic engine is greatest when the current is indefinitely small, and then the rate at which it works is also indefinitely small.
To secure fairly uniform efficiency in the various corps, and also as a means of unifying Italy, Piedmontese, Umbrians and Neapolitans are mixed in the same corps and sleep in the same barrack room.
The Rocket possessed the three elements of efficiency of the modern locomotive - the internal water-surrounded fire-box and the multitubular flue in the boiler; the blast-pipe, by which the steam after doing its work in the cylinders was exhausted up the chimney, and thus served to increase the draught and promote the rapid combustion of the fuel; and the direct connexion of the steam cylinders, one on each side of the engine, with the two driving wheels mounted on one axle.
Per pound, the maximum indicated horse-power is given by the expression I.H.P. maximum - CcA X778 1980000 where A is the area of the grate in square feet, and is the combined efficiency of the engine and boiler.
Engine efficiency depends upon many variable factors, such as the cut-off, the piston speed, the initial temperature of the steam, the final temperature of the steam, the quality of the steam, the sizes of the steam-pipes, ports and passages, the arrangement of the cylinders and its effect on condensation, the mechanical perfection of the steam-distributing gear, the tightness of the piston, &c. A few values of the thermal efficiency obtained from experiments are given in Table XXI.
In the second column, the first column being added to give some idea of the rate at which the engine was working when the data from which the efficiency has been deduced were observed.
Table Xxi It is instructive to inquire into the limiting efficiency of an engine consistent with the conditions under which it is working, because in no case can the efficiency of a steam-engine exceed a certain value which depends upon the temperatures at which it receives and rejects heat.
The standard of comparison generally adopted for this purpose is obtained by calculating the efficiency of an engine working according to the Rankine cycle.
When the initial pressure is 100 lb per square inch by the gauge the thermal efficiency drops to about nearly 15% with the same back pressure.
During the Russo-Japanese War he served in the Red Cross and in the Municipal Union for the organization of hospitals; he was left to take care of the Russian wounded after the battle of Moukden, and showed much dignity and efficiency in the performance of his arduous duties.
And in this efficiency that is generated by specialization, wealth is created.
The gains in efficiency obtained through this approach are one reason that cities are such powerful economic units: Cities bring people into proximity to each other and facilitate specialization and trade.
Lowering the cost of something is an increase in efficiency and an increase in the wealth of the overall system.
If he replaces the job with another $10-an-hour job, then you must admit there was a true efficiency gain.
And you could feel good about it; after all, you would be increasing efficiency, not merely acting as a leech to the system.
However, there are limits to how much prosperity and efficiency the division of labor can create.
I branched off into this discussion of robots and nanites to give an idea of the kinds of massive gains in efficiency with declining costs.
Operating at basically 5 percent efficiency, they are less than half as efficient as solar panels now on the market.
But the food would not only be produced with maximum efficiency; it would be extremely fresh and very healthy.
In an article in The Economic Times, a British cabinet office minister said that the United Kingdom government "is determined to have the most ambitious open data agenda of any government in the world ... in order to create public accountability and efficiency in our services and to drive economic and social growth."
He went up to the map and speaking rapidly began proving that no eventuality could alter the efficiency of the Drissa camp, that everything had been foreseen, and that if the enemy were really going to outflank it, the enemy would inevitably be destroyed.
