V, and the points of junction of these lineswith the vertical lines will be points in the theoretical curve.It will now be an easy matter to trace the curve throughthese points. If, on the other hand, it be desired to com-pare the curves toward the exhaust end of the diagram,draw lines E D and E T,… … Fig. 215 diagonal T V, proceed in the same manner as before tolocate the intermediate points. It will be observed that in order to ascertain the perform-ance of the steam near the beginning of the stroke, thestarting point of the isothermal curve must be near thepoint of release, and conversely, if…
