Trace the arrow mark, starting with F for cooling temperature 25C (pressure dew point 25C) to find the intersection G on the pressure characteristic line for 0.7 MPa. 8. From the intersection G, trace the arrow mark to obtain the intersection H on the vertical axis. 9. The intersection H is the amount of water included in the compressed air 1 m3 at 0.7 MPa, pressure dew point of 25C.
