Valve Sizing - 2 way General Service Valves
 
STEP 1 : Select Gas
 
 
STEP 2 : Enter Gas Temperature, Inlet Pressure and Specific Gravity
  For proper mass flow conversion (LB/HR to SCFH), enter Specific Gravity at standard atmospheric conditions (20oC / 70oF)
*Heat Value is only used when Flow Rate is expressed in BTU/HR.
  Temperature  oF
  Inlet Pressure PSIG Inches of water column
  Specific Gravity
  *Heat Value  BTU/FT3
 
STEP 3 : Select Parameter to be Calculated and Enter Remaining Two
  Flow Rate SCFH LB/HR BTU/HR*
  Pressure Drop PSI Inches of water column
  Flow Coefficient  Cv
