xpulsion stroke the exhaust-valve closes, the admission-valve opens, the pressure falls fromJ to A, and the cycle is completed. Fig. 44 is a representation of the T- 9 diagram, plotted fromthe p-v diagram, as shown in Fig. 43. Assuming the temper-ature at the point B, Fig. 43, to be equal to that… … Fig. 44. where the curves, representing compression and expulsion, inter-sect, was assumed. Then by substituting in equation (14), thevalues of pressure and volume, as found by scale, from thep-v diagram, for the various points, the entropy, correspondingto these points, was readily computed. The…
