TecQuipment’s Fluid Friction Apparatus allows students to study flow, flow measurement techniques and losses in a wide variety of pipes and fittings. 

The equipment has three water circuits with instruments, pipes and pipe system components. These allow students to examine and compare the different component characteristics. The Digital Hydraulic Bench (H1F, available separately) supplies the circuit with a controlled flow of water. A space-saving vertical panel holds all the parts for easy use. 

To measure pressure loss across components, students use a piezometer set and differential pressure gauge (included). 

To perform experiments students record the temperature of water in the hydraulic bench and set the hydraulic bench to pump water through a circuit. They measure pressure losses across instruments or components. The hydraulic bench gives an external flow rate for reference and comparison. 

The flow measurement instruments show students the common methods of measuring water flow. They also give applications of the steady flow energy equation (Bernoulli’s equation). Students use a Venturi meter and an orifice plate meter and compare the losses of each. They also find the losses in a rapid enlargement. 

The equipment also includes a Pitot-static tube. By traversing the Pitot across the pipe diameter, students can find the velocity profile and flow coefficients. They also find the relationship between the flow rate and pressure differential.

An artificially roughened pipe allows students to study friction factor at different Reynolds numbers. They can compare results to those predicted by Nickuradse’s results and a Moody chart.

H1F - Base Unit

Provides a controlled recirculating water supply and accurate flowmeter for hydraulic and fluid mechanics experiments.

H16 - Experiment

An apparatus to allow students to investigate the friction losses in piping systems. The large open format of the apparatus makes it ideal for students working in small or large groups.

H34 - Experiment

A simple single pipeline apparatus to demonstrate energy losses around typical bends and fittings.

H40 - Experiment

A compact unit that compares and shows the accuracy, losses and use of fundamental flow meters. Includes a nozzle flow meter as standard.

H5 - Experiment

An educational Venturi tube that allows students to study the Venturi meter and Bernoulli's Theorem and to make direct comparisons between the results obtained by experimentation and those predicted by theory.

H7 - Experiment

A bench-mounting apparatus to allow students to investigate friction losses in a small-bore horizontal pipe under laminar and turbulent flow conditions.

H10 - Experiment

Investigates different ways of measuring flow including a Venturi meter, an orifice plate and a rotameter. At the same time shows applications of the steady flow energy equation (Bernoulli's equation).
