Not illustrated. 1832 Excerpt: ...of steam. The quantity of water, or weight of steam, which can be evaporated in a given time, will, therefore, give the true measure of effect: and having once in any engine, ascertained the greatest quantity of steam which can be raised per minute, we can then calculate the effect which can be IIP produced. This will be R = 4--where R = velocity of the piston per minute, / -= the length of the stroke, P = the pressure acting upon the piston, over and above what balances W; and Wathe resistance, acting against the free motion of the piston. We shall now endeavour to ascertain, from the foregoing experiments, the actual performance of locomotive engines, with respect to the quantity of goods which they may be expected to drag upon Rail-roads. On examining Experiments II. and III., we find one engine take 36 tons of goods, at the rate of five miles per hour; and 48 tons, at the rate of 4f miles per hour. This was effected by an engine, the area to the fire-place of which, was 6 square feet; the surface exposed to the radiant heat of the fire, being 10 square feet; and to the flame and heated air, 21 square feet In Experiment V., the area of the fire-place of which was 7 square feet, the surface exposed to radiant heat, 11 square feet; and to the communicative heat of the flame on its pas sage to the chimney, 29f square feet, being above one-third more; and hence we find the effect correspondingly increased The performance of the latter engine is 48 tons, conveyed at the rate of 6,6 miles per hour, which, as the relative resistance, in the most favourable, and most unfavourable weather, has been shown to be as 4: 3: in the first edition of this work, the performance was called in practice, 40 tons, moved at the rate of six miles per hour.
