It is a common practice to multiply the area of the air piston by the dis-tance it travels in a minute, and to state such amount as the free air capacityof the Compressor. To ascertain the bulk of air in the compressed form, it isnecessary to add 15 lbs. to the gauge pressure, divide the amount by 15 andthe result will be the number of atmospheres in the air of that pressure. Thefree air capacity of the Compressor divided by the number of atmosphereswill give the amount of air after compression. This amoun

Thefree air capacity of the Compressor divided by the number of atmosphereswill give the amount of air after compression. This amount must be reducedby allowances of various kinds. The losses due to poor designing and work-mansliip, the use of warm induction air, insufficient supply, losses in clearanceand leaks, may be quite serious. In some machines these losses amount to aclear 30 per cent, of their theoretical capacity, whereas ten per cent, shouldbe liberal for all ordinary contingencies. We have shown how some lossesare avoided and others reduced to the least possible in the Norw
