1. Modeling Flow Meters with Compressible Fluids in PIPE-FLO Professional
   PIPE-FLO Professional has certain limitations concerning the use of compressible fluids in a piping network. The limits of the Darcy Weisbach equation pertaining to compressible fluids are covered on page 18 of the Method of Solution for PIPE-FLO and elsewhere in this knowledge base. Even when o ...
2. Flow Meter Sizing Module Overview
   With PIPE-FLO's flow meter sizing module, you can size and evaluate flat plate concentric orifice meters, venturi meters, and nozzle meters. You can also create user defined meters by entering a discharge coefficient, enabling you to analyze any type of differential pressure meter. There are a ...
3. Modeling a Flow Meter in PIPE-FLO 2005
   A flow meter can be modeled in PIPE-FLO 2005 as either a fixed K value or as a component. If you are using a fixed K value, you can enter it directly or you can calculate the K value using the dP Calculator feature. The three methods are outlined below. If the flow meter K value is known, it ca ...
4. Meter Sizing in Design Mode
   When flow meters (including Balancing Orifice, Metering Orifice, Venturi Tubes, and Nozzles) are sized, there exist instances where a meter can be sized in calculated mode, but can not be sized in design mode due to flashing conditions. When flow meters are sized, the inlet pressure is used to d ...
5. Sizing a Minimum Flow Recirculation Line
   Most pumps have a minimum flow rate that they should not operate below. The pump manufacturer provides this value. Operating a pump below the specified minimum flow rate can greatly reduce a pump's life. Typical problems that can occur with sustained operation below the minimum flow are excessiv ...
6. Sizing Balancing Orifices
   In the system below, the flow rate required in each distribution line is 300 gpm. In order to reduce the system cost and complexity, the same control valve is installed in all three distribution lines. For the design flow rate, the particular valve we will be using has a controlling range of 5 ...
