Bulletin: 2013-009

Date: 06-12-2013

Category: 2

Program affected: PIPE-FLO Professional 12

Build numbers affected: 12.0.19520

Approved by: RL

Background
The operating point displayed on the pump graph is wrong for a Centrifugal Pump set to variable speed if the design and document flow rate units are not the same. E.g., if the variable speed flow rate is entered as 100 gpm and the document units are set to L/min, then the operating point will be displayed at 100 L/min.

Condition
Both conditions must be met:

  • You have graphed a Centrifugal Pump set to variable speed. 
  • The design unit for the pump's set flow rate is different than the flow rate unit set in the document units dialog.

Workaround
Set the document and design flow rate units the same before graphing the pump.
