PFR Releases FRNC-5PC Version 9.4.0

On February 26, 2019, PFR Engineering released FRNC-5PC v9.4. Version 9.4 includes a number of enhancements, upgrades and new features. Following are some highlights:

  1. Added option to fix the Process Stream Phase condition at the Inlet and/or Exit (all-Liquid, all-Vapor, or 2-Phase vapor fraction).
  2. Added option to specify a Coil’s radiation “Alpha” value, to override the program calculated value.
  3. Enhanced the output tube-by-tube printout to include Liquid and Vapor physical properties. This will help when manually checking the calculated film coefficients and pressure drops.
  4. Added Tube Thickness design parameters to output, to help understand the calculated Required Tube Thickness values.
