This equipment consists of a hydraulic circuit including pump and flowmeter and enabling to be connected with various hydraulic components, where the pressure drops on these elements can be measured. The automated version includes a PID controller for the automatic control of the flow rate of the water crossing the circuit.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Determining pressure drops in pipes of different diameter
• Determining pressure drops in bends and elbows
• Determining pressure drops in pipe expansions and restrictions
• Measuring the flow rate with calibrated orifice and computing the discharge coefficient α
• Measuring the flow rate with Venturi tube and computing the discharge coefficient α
• Checking the laminar, transition and turbulent flows by tracer
• Verifying Bernoulli’s theorem
