Not illustrated. 1875 edition. Excerpt: ... l-93 times greater, the initial pressure in this cylinder will be 7-l1bs, and the terminal pressure 4-731bs. This will give 17-98, or, say 18 expansions. Now the high pressure cylinder, with a terminal pressure of 13711b, and cut-off at one 6-2 of the stroke, will give an average absolute pressure of 88-7171bs; but as the initial pressure in the low pressure cylinder is 7I-1bs, so this will be the back pressure, which must be deducted from 387171bs, leaving 31-6171bs as the average effective pressure on the piston. The low pressure cylinder, with a terminal pressure of 4-731bs, and the cut-off at two-thirds of the stroke, will give an average of 6-6451bs, from which we deduct 21bs back pressure (making it equal to a vacuum of 131bs), giving an average effective pressure of 4-6451bs. The result can now be expressed by the equations, 33000 Together making = 144-018 H.P. The measurement of steam used to the point of cut-off in the high pressure cylinder was one 6"2 (or 0-1613) of 60 inches = 9677 inches X 806 in area = 2,961 cubic inches. Ijet us now see what will be the power given out by the same initial pressure of steam, the same cubic capacity, and the same ratio of expansion, and therefore the same terminal pressure, --arranged according to the rule of proportion for Compound Eijgines given in chapter on compounding. The low pressure being taken as the standard for the power required, the cylinder will be 900 inches area as before. As the steam is expanded 18 times, the high pressure cylinder will require to be 210 inches area, and the point of cut-off will be one 425 or at 1411 inches. This will give 2,961 cubic inches measurement as before. Then 851bs initial pressure, cut off at one 4"25, will give a terminal pressure of...

Excerpt from The Steam-Engine Indicator, and Its Use: A Guide to Practical Working Engineers for Greater Economy and the Better Working of Steam-Engines The term element, as used, means a body which cannot, as far as we know, be divided or decomposed. It is unalterable and indestructible, and therefore called a simple body, or element. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
