What is the difference between Francis turbine and modern Francis turbine? According to type of flow
Francis turbine is radial flow turbine but in case of modern Francis turbine water enters radially and leaves the turbine axially which is called as mixed flow turbine.

Is modern Francis turbine radial flow turbine?

Radial flow turbines: In this type of turbines, the water strikes in the radial direction. Accordingly, it is further classified as: Inward flow turbine: The flow is inward from the periphery to the centre (centripetal type). Example: old Francis turbine.

What are the difference between Kaplan and Francis turbine determine the efficiency of Francis turbine test rig?

Efficiency of the Francis turbine is smaller in comparison with the Kaplan turbine. Efficiency of the Kaplan turbine is more than the Francis turbine. This turbine is efficient over a wide range of water head and flow rate. The size of the Francis turbine is approximately large in comparison with the Kaplan turbine.

What are the changes between the original Francis turbine and the modern version also derive the degree of reaction for a Francis turbine?

According to type of flow
Francis turbine is radial flow turbine but in case of modern Francis turbine water enters radially and leaves the turbine axially which is called as mixed flow turbine. Kaplan turbine is axial flow turbine i.e. water enters and leaves the turbine runner both in axial direction.

What is the difference between Francis Pelton and Kaplan turbine?

The basic difference between Pelton, Francis and Kaplan Turbines is explained in this article. Francis Turbine is an inward flow reaction turbine. Kaplan turbine is a propeller type reaction turbine. The operating water head of a Francis turbine ranges from 40 to 600m.

Which type of turbine is modern Francis turbine?

The Francis turbine is a reaction turbine, which means that the working fluid changes pressure as it moves through the turbine, giving up its energy. The turbine is located between the high-pressure water source and the low-pressure water exit, usually at the base of a dam.

Which turbine is radial flow turbine?

A radial turbine is a turbine in which the flow of the working fluid is radial to the shaft. The difference between axial and radial turbines consists in the way the fluid flows through the components (compressor and turbine).

What is the difference between Kaplan turbine and Francis turbine?

Efficiency of Kaplan turbine is higher than Francis turbine. Kaplan turbine is more compact in cross-section and has lower rotational speed to that of Francis turbine. In Kaplan turbine, the water flows axially in and axially out while in Francis turbine it is radially in and axially out.

Is Francis turbine an impulse turbine?

Francis turbine definition is a combination of both impulse and reaction turbine, where the blades rotate using both reaction and impulse force of water flowing through them producing electricity more efficiently.
