Fig. 9.—Construction of the adiabatic curve. COMPRESSED AIR 455 due to the adiabatic curve at the corresponding ordinate of the indi-cator card. The diagram is applicable to high and low pressure cardsalike, the proper initial absolute pressure being taken, of course. For compression from 14.7 lbs.… … Fig, 5.—Compressed air indicator card analyzed by the chart. Fig. 6. diagram, from which the pressures at the various ordinates may beread directly for that initial pressure. The use of this initial pressure is, however, seldom justified be-cause of the suction loss which exists in most cases. In…
