Engineering 24.99X3.125-^3.25=:24.03 pounds, which is the correctedrate and represents a saving by compression of 24.99—24.03r=.96 pounds, or nearly 3.7 per cent. In many cases 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 uncorrected rate by just somuch; as for instance, terminal pressures34 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…
