Fluid Science Flow Measurement

Utilising the service unit the flow meters experiment rapidly mounts onto the multi functional work panel and is connected to the built-in water supply via quick connect couplings. Differential pressure reading is taken using a digital manometer against varying flow rates.
Combined with the Fluid Science Service Unit, the Fluid Science Flow Measurement Tray, provide shands on experimentation designed to demonstrate flow measurement and the relationship between velocity and pressure drop.

Thetray includes the following flow meters:
Orifice plate The use of anorifice plate to measure flow is demonstrated by measuring the pressure dropacross a defined orifice. The geometry of the orifice is in accordance with standard industrial orifice flow meters.
Venturi Meter : Used to demonstrate Bernoull is equation, showing how low pressure is generated in the throat of aventure tube, and how this is affected by flow. Thegeometry of the venturi orifice is in accordance with standard industrial venturi flow meters, so the use of a venturi to measure flow can also bedemonstrated. The flow recovery is also demonstrated by measuring the total pressure drop across the module.

Types of flow measurement and its application
Explain the principles of a venturi meter and an orifice meter and why one is selectedover the other in certain applications.
Mechanical energy balance on a venturi meter
Comparepressure drop across the entrance and exit of the meter (i.e. P acrossentrance /throat and P across throat/ exit) and explain results.
Pressure and velocity changes through a venture meter
i.e.increased velocity results in reduced pressure
Energy transition in a venturi and orifice plate meter
Explainthe term vena contract, why it occurs in an orifice meter and its result(i.e. its permanent pressure
Explain the importance of discharge coefficient and calculate ideal flow rate across the both meters.
