I need support to estimate the pressure drop cross a Fisher valve for flow rate at

50 MMSCFD.

40 MMSCFD.

30 MMSCFD.

25 MMSCFD.

20 MMSCFD.

15 MMSCFD.

for the following valve and process conditions:

  • Service Natural Gas
  • Specific gravity 0.655
  • Inlet pressure 430 psig.
  • Inlet temperature 100 deg.F
  • Made Fisher.
  • Size 2”.
  • Type ES.
  • Port 2 5/16.
  • Char-  equal percentage.
