Hopgood, D. 2001. Accuracy limits for these expansion curves have been tested by Loh et al., 23 who found, for example, that the allowable 0.6-gravity gas expansion from 23.8 MPa (3,500 psia) and 338 K (150F) should be 2.8 MPa (410 psia), rather than the value of 4.76 MPa (700 psia) given by Fig.5. In expansion processes, the upstream temperature and pressure are known, but the discharge temperature usually is unknown, and a downstream vessel normally sets the discharge pressure. The gas flowing through the pipeline is cooled to 38F by the surrounding water. (w2 = b - c) 4. FOIA. Digital Marketing by This is the error.
