Three Ways to Accurately Model Tee Fittings Using PIPE-FLO®

Users often inquire about the correct way to account for the losses through a Tee fitting. PIPE-FLO® Professional utilizes the fitting methods described in the Crane Technical Paper 410: Flow of Fluids Through Valves, Fittings and Pipes. The TP-410 provides just two L/D values for Tees that are used to calculate the K resistance values; 20 for Flow Thru Run and 60 for Flow Thru Branch. The TP-410 offers no further information about how to apply these values, as that is all of the information needed to solve for a single flow path. However, confusion comes about when trying to determine how to incorporate these values into a PIPE-FLO® model where we are solving multiple paths simultaneously. For some applications, the losses through Tees are insignificant and for other applications the TP-410 method may be too general, and more geometry specific methods are desirable. Ultimately, the choice of method is based in the engineering judgement of the user, but we will cover several options to model these Tees in PIPE-FLO®.

Penn State Engineering Students Use PIPE-FLO® and Vibration Technology to Solve Cavitation Issues

Engineered Software, Inc. and KCF Technologies Inc. recently presented a case study at the 2015 Chem Show in New York City. What made this project so much fun is that it was a Capstone Project conducted by a group of engineering students at Penn State. The students were evaluating the cause of a major cavitation problem at the University Area Joint Authority (UAJA) pumping station in State College, PA.

Accurately Modeling Pulp and Paper Piping Systems With the PIPE-FLO® Stock Module

Accurately modeling a pulp and paper slurry piping system can be difficult without the proper tools and equations. This difficulty is caused because slurries do not act in the same manner that water in pipelines does. This phenomenon is known as Drag Reduction. In the upcoming release of PIPE-FLO® Professional, users can accurately model stock fluid using the method described below.

PUMP-FLO® Connect Optimizes Pump Selection with New Multiple Operating Points & SRC Feature

With PUMP-FLO® Connect, users have the option of specifying additional operating points and system resistance curves to be displayed in the pump’s graph windows. This includes operating points with different static and total heads, or even with different flows. Data inserted in the operating points interface is entirely up to the user. While these points are not used as criteria for pump selection, the standard warning messages will apply if these points are outside of the pump’s limits.

When Should You Use the HSS vs the HX 2-Pipe Device?

Both of the new devices added in PIPE-FLO® Professional version 15 can model real-world processes that facilitate sensible heat transfer in flowing fluids. The heat source/sink device is used to model heat transferred into or out of a single fluid, whereas the heat exchanger 2-pipe device is used to model sensible heat transfer between two fluids. Both devices model the hydraulic performance of only one side of a heat exchanger.

How to Use the Flow Control Device in PIPE-FLO® v15

Two new devices have been added to PIPE-FLO® Professional version 15 to perform a thermal analysis of heat exchangers used in a wide variety of applications throughout various industries. The heat source/sink device and the heat exchanger 2-pipe device are used to evaluate sensible heat transfer into, out of or between flowing fluids. One of the optional design data fields for these two devices is the flow control device (FCD). Assigning an FCD establishes a process control link to another device in the piping system model to regulate the flow rate through the heat transfer device. It, therefore, controls the heat transfer rate, inlet temperature or outlet temperature as well.

Maximizing Pump Modeling with All-New Pump Operating Modes

PIPE-FLO® Professional Version 15 incorporates several improvements to existing features as well as all-new heat transfer functionality, 15 new calculations and enhanced reporting and automatic solutions for several over-controlled scenarios. One of the new features in PIPE-FLO® Professional v15 is the addition of three new operating modes for the centrifugal pump and sizing pump devices. The new discharge pressure, suction pressure and temperature control operating modes provide more flexibility for the user to model real-world process controls and evaluate system performance in PIPE-FLO®.
