Equipment Description

The FM-204 experimental unit consists of a pipe section incorporating several elements with different flow resistances, as well as contraction and expansion sections. A ball valve is also integrated into the system.

Pressure measuring points equipped with annular chambers are positioned upstream and downstream of the pipe elements to ensure accurate pressure measurements.

These measuring points can be connected in pairs to six tube manometers, allowing the determination of pressure losses across each piping element.

Reference : FM-100.10

General Description

The FM-100.10 is an educational and experimental unit designed to study forces generated by fluid jets. When a flowing fluid is accelerated, decelerated, or deflected, its velocity changes, resulting in a variation of momentum and consequently producing measurable forces.

In practical engineering applications, these forces are used to convert kinetic energy into mechanical work, such as in Pelton turbines.

Operating Principle

The unit generates a water jet directed at interchangeable deflectors. The jet is deflected at different angles, producing forces that can be measured.

The jet force is adjusted by varying the flow rate. Experiments allow investigation of:

• The influence of flow velocity
• The effect of flow rate
• The impact of different deflection angles

Measured forces are compared with theoretical values calculated using the momentum equation.

Scope of Delivery

• Transparent tank for visual observation
• Nozzle for jet generation
• 4 interchangeable deflectors
• Weight-loaded scale for force measurement
• Set of calibrated weights

Installation & Compatibility

Référence : FM-100.12

General Description

The FM-100.12 experimental unit is designed for the detailed study of pressure losses in pipes under both laminar and turbulent flow conditions. During fluid flow through pipes, pressure losses occur due to internal fluid friction as well as friction between the fluid and the pipe wall.

This unit enables the determination of the friction factor, a dimensionless parameter essential for calculating pressure losses. The friction factor is closely related to the Reynolds number, which represents the ratio of inertial forces to viscous forces.

The system allows analysis of the relationship between pressure loss and flow velocity, as well as experimental determination and comparison of friction factors with theoretical values.

Operating Principle

The unit includes a small-diameter pipe section where both laminar and turbulent flows can be generated. The Reynolds number and friction factor are determined based on measured flow rate and pressure losses.

In turbulent flow conditions, the pipe is directly supplied from the water network. For laminar flow, a constant pressure is maintained using a standpipe with overflow. Flow rate is controlled using valves.

Experiments

• Measurement of pressure losses in laminar flow
• Measurement of pressure losses in turbulent flow
• Determination of critical Reynolds number
• Determination of pipe friction factor
• Comparison of experimental and theoretical friction factors
