oportion is obviouslyas follows: Velocity of piston : mean velocity of extremity of crank :: twicethe length of stroke : circumference which the extremity of thecrank describes. Let / denote the length of stroke, and ir the ratio of the circum-ference of a circle to its diameter; then we have the… … MECHANICAL POWER OF STEAM 373 :rank is greater than that of the piston, then, according to our law, in order to produce the same mechan-ical effect, the mean effective pressure must be less, and that in the same proportion. We may approxi-mate tn the mean effective pressure by calculating it for a…
