This page contains a set of technical training videos that explain and demonstrate how to use the Pipe Flow Expert software to calculate fluid flow rates, calculate pressure losses, calculate pump head requirements and check the overall operating performance of your pipe system.These training videos demonstrate how to use the Pipe Flow Expert Software to model different items.

## Pipe Flow Expert - Tanks

Pipe Flow Expert Software Demonstration of modeling fluid flow between two tanks with different levels of fluid.

Modelling and solving the classic Three Reservoirs problem using Pipe Flow Expert.

## Pipe Flow Expert - Fittings

Modeling flow in a series of pipes and fittings as an equivalent single pipe with multiple fittings.

Demonstration of how to model contractions and enlargement fittings using Pipe Flow Expert.

Modeling flow through branching pipe system with through tees and branch tees.

## Pipe Flow Expert - Flow Demands

Modeling flow demands at nodes, to represent in-flow and out-flow from the system, using Pipe Flow Expert.

## Pipe Flow Expert - Pumps

Adding a pump in a pipe system: as a fixed flow pump (where the software calculates the pump head required), or as a fixed head [pressure increase] pump (where the software calculates the flow rate that will occur), or as a fixed speed pump that operates on a flow versus head performance curve.

Demonstrates how to add a pump with a fixed head increase in a pipe system modeled using the Pipe Flow Expert software, so that the system can be calculated and solved to find the resulting flow rate.

This video shows how to add a pump with a specified fixed flow rate in a model of piping system. The Pipe Flow Expert software then calculates the pump head required in order to achieve the given flow rate, when considering all of the other flows and pressures throughout the system.

How to add a pump with a flow versus head curve in a model of a pipe system. The Pipe Flow Expert software solves the system and calculates the duty point, i.e. it calculates and shows the operating point on the pump curve, giving the flow rate and pump head that will occur when the system is up and running.

How to define a single pump curve that can then be used to predict the pump performance graph across a range of speeds and impeller sizes. The Pipe Flow Expert software also allows further customization of the pump graph predictions to match exactly against the pump graph provided by the pump manufacturer.

Import a pump graph in to the Pipe Flow Expert software. Load a photo or image of the pump curve and then trace over the curve to define the pump performance as a series of data points for the flow rate and pump head values.

How to adjust the pump curve model within the Pipe Flow Expert software so that the pump performance data and efficiency lines exactly match the data as provided on a pump manufacturer's performance graph.

This video shows how to search the pump database within the Pipe Flow Expert software to select a pump that meets a required flow rate at a specific pump head.

Calculate the effect on flow rate and pump head requirements in a pipe system when the pump speed and impeller size are changed.
