Engineering 24.99X3.125^e3.25==24.03 pounds, which is the correctedrate and represents a saving by compression of 24.99—24.03=.96 pounds, or nearly 3.7 per cent. In many eases the terminal pressure greatly exceeds thecompression, an illustration of which is given in Fig. 209which is a reproduction… … Fig. 210 becomes longer than the stroke line E. M., therefore thecorrected rate will exceed the uncoriected rate by just somuch; as for instance, terminal pressure=34 pounds. Thefactor, as per Table 34,=1152.26, and the M. E. P. of thediagram is 47 pounds. Then, 1,152.26-^47=24.5 pounds,uncorrected…
