The Francis Turbine, a type of reaction turbine developed by Sir J.B. Francis, is a crucial machine in hydropower generation. It is classified as a mixed-flow turbine because water enters the runner radially through the outer periphery and exits axially. A defining characteristic is that as water flows through the runner, a portion of its pressure energy continuously converts to kinetic energy, meaning the runner is always under positive pressure. The runner is fully enclosed in an airtight casing that remains filled with water. This experimental setup is designed to study the performance of the Francis turbine, using a Centrifugal Pump to feed water radially to the runner. The unit includes a guide mechanism and a draught tube at the outlet. A brake arrangement (dynamometer) is connected to the shaft to apply a load, which is necessary for calculating power and efficiency.
