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.
