While these assets upgraded our efficiency, the LeBlanc house continued to be inadequate.
The lime deposit or " fur " is a poor conductor of heat, and it is therefore most detrimental to the efficiency of the system to allow the interior of the boiler or any other portion to become furred up. Further, if not removed, the fur will in a short time bring about a fracture in the boiler.
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.
The main features of the steam locomotive were thus established, and its subsequent development is chiefly a history of gradual increase in size and power, and of improvements in design, in material and in mechanical construction, tending to increased efficiency and economy of operation.
The relative merit of the two systems depends upon the question how we can secure the best efficiency and equity in the application of the principles thus far laid down.
Whether the intelligence and efficiency of the officials charged by the state with the handling of its railway system will be sufficient to make them act in the interest of the public as fully as do the managers of private corporations, is a question whose answer can only be determined by actual experience in each case.
When a line has once been inspected and passed, it lies with the company to maintain it in accordance with the standard of efficiency it originally possessed, but no express statutory obligation to do so is imposed upon the company, and whether it does so or not, the Board of Trade cannot interfere.
Collisions, on the other hand, are preventable, and derailments nearly so, and the records of deaths and injuries in this class in successive years are therefore justly taken as an index to the efficiency with which the railways are managed.
A few experimental results are set forth in Table XX., from which it will be seen that with a relatively low rate of combustion, a rate which denotes very light service, namely lb of coal per square foot of grate per hour, the efficiency of the boiler is %, which is as good a result as can be obtained with the best class of stationary boiler or marine boiler even when using economizers.
Hence assuming the mechanical efficiency of the engine to be and substituting !
Per hour, the tractive force falls to 7400 lb, and this cannot be increased except by increasing the rate of combustion (neglecting any small changes due to a change in the efficiency 7 Knowing the magnitude of R, the draw-bar pull, and hence the weight of vehicle the engine can haul at this speed, can be estimated if the resistances are known.
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.
The standard of comparison generally adopted for this purpose is obtained by calculating the efficiency of an engine working according to the Rankine cycle.
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.
