Page 166 - Isothermal," or the pressure curve uninfluenced by heat. The three curves which begin at the lower left hand corner and rise to the right, are heat curves and represent the increase of temperature corresponding with different pressures and volumes, assuming in one case that the temperature of the air before admission to the compressor is zero, in another sixty degrees, and in another one hundred degrees. Beginning with the adiabatic curve, we find that for one volume of air. when compressed without...
Page 146 - It was the opinion of this committee that a boiler rated at any stated power should be capable of developing that power with easy firing, moderate draught, and ordinary fuel, while exhibiting good economy, and at least one-third more than its rated power to meet emergencies.
