Description :
- Francis Turbine is a reaction turbine, which was developed by an English born American Engineer Sir J. B. Francis.
- The water enters the turbine through the outer periphery of the runner in the radial direction and leaves the runner in axial direction and hence it is called a mixed flow turbine.
- As the water flows to the runner, a part of pressure energy goes on changing into kinetic energy.
- Thus the water through the runner is under pressure.
- The runner is completely enclosed in an air tight casing and the casing & runner is always full of water.
- The present set-up consists of a runner. The water is fed to the turbine by means of Centrifugal Pump, radially to the runner.
- The runner is directly mounted on one end of a central SS shaft and other end is connected to a brake arrangement.
- The circular window of the turbine casing is provided with a transparent acrylic sheet for observation of flow on to the runner.
- This runner assembly is supported by thick cast iron pedestal.Load is applied to the turbine with the help of brake arrangement so that the efficiency of the turbine can be calculated.
- A draught tube is fitted on the outlet of the turbine. The set-up is complete with guide mechanism. Pressure and Vacuum gauges are fitted at the inlet and outlet of the turbine to measure the total supply head on the turbine.

FAQs of Francis Turbine Test Rig:
Q: How is flow measured in the Francis Turbine Test Rig?
A: Flow is measured using either a rotameter or an electromagnetic flow meter, ensuring precise monitoring of water discharge within a measurement range of 0200 liters per minute.
Q: What installation requirements are needed for setting up the Francis Turbine Test Rig?
A: A levelled floor, single-phase or three-phase power supply (220V/440V AC), and an adequate water source are necessary to install and operate the test rig effectively.
Q: When should the overload and dry run protection features be used?
A: These safety features automatically activate during abnormal load or insufficient water conditions, preventing equipment damage and ensuring operator protection during experimentation.
Q: Where is the Francis Turbine Test Rig typically used?
A: This rig is primarily used in hydraulic and fluid mechanics laboratories at academic institutions and engineering training centers across India for practical performance and efficiency measurement experiments.
Q: What benefits does the computer interface offer for data acquisition?
A: The optional computer interface enables automated data logging and analysis, helping users generate detailed performance curves and streamline experiment documentation for research and instructional purposes.
Q: How is shaft power measured in the test rig?
A: Shaft power is determined directly using an integrated dynamometer, which provides real-time, precise readings of the turbines output power during testing.
Q: What is the process for conducting efficiency tests on the Francis Turbine Test Rig?
A: Begin by adjusting the guide vanes to set operating conditions, measure input/output parameters using built-in digital meters, and collect discharge, pressure, and RPM data. Calculate efficiency using the measured values, either manually or with data acquisition software.
