Francis Turbine Test Set

Description of Francis Turbine Test Set

The Francis Turbine Test Set is designed for studying the Francis turbine characteristics under various flow rates and heads. The unit consists of a storage tank, a pump, a turbine, a dynamometer, a generator, and measuring instruments. The adjustable guide vanes direct water to the runner. Power output at various flow rates, heads and speeds can be measured by either dynamometer or generator. The unit is on wheels.

Experiments of Francis Turbine Test Set

1. Torque vs speed at various heads and flow rates.
2. Power output vs speed for various heads and flow rates.
3. Efficiency vs speed for a given head and flow rate.
4. Overall turbine generator efficiency.
5. Racing characteristics.
