A better result in be obtained by using the condensing Lasmuch as the friction and conden steam of the high-pressure cylinder d. Supposing that the steam in the oylinder was cut off at half the stroke, b expand the remainder, which would be ) termination; this 34Ibs would be 1 the piston of the low-pressure cylinder: ert a resisting force on the high-pressure to the force on the low-pressure piston. uld, in fact, balance each other; therefore would be obtained by passing the steam high to the low-pressure cylinder, beyond int of vacuum obtained by the condensation; could be equally effected with one cylinder. advantage of the unequal diameter cylinders 'be as follows: --the steam admitted at 50fcs atmospheric pressure, or, in reality, 651bs Sm, would, by operating first in the small cylinder me full length of the stroke, pass thence to the vd cylinder, where it would expand eight times ler bulk--that is, until it was reduced to a e of 81bs per square inch at the end of the or 7 J1"--the atmosphere; in this case, ok' s 65Ibs steam is made available, i n the preceding page is calculated for the stroke, with a pressure in the boiler square inch. The small cylinder of the 'ngine is assumed to be of one inch area; e one of six inches area, with a six-inch sequently, the steam cut off at one-sixth cylinder will be equal to the whole area ents of the small high-pressure cylinder. 1 expresses the number of inches the piston 1; column 2, the difference of pressure ston for each inch of the stroke; column 3 I power operating upon the large piston at a of the stroke; column 4, the...
