According to the direction of flow through the runner, the turbine is classified as:
View all questions of this test
- Tangential flow turbines: In this type of turbine, the water strikes the runner in the direction of the tangent to the wheel. Example: Pelton wheel turbine
- Radial flow turbines: In this type of turbine, 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.
Outward flow turbine: The flow is outward from the centre to the periphery (centrifugal type)—example: Fourneyron turbine.
- Axial flow turbine: The water flow is parallel to the shaft axis—for example, direction arcine and propeller turbine.
- Mixed flow turbine: The water enters the runner in the radial direction and leaves in an axial direction. Example: Modern Francis turbine

The correct answer is option 'C' - The water enters the wheel at the outer periphery and then flows towards the centre of the wheel.
In an inward flow reaction turbine, the water enters the turbine at the outer periphery and then flows towards the centre of the wheel. This type of turbine is also known as a Francis turbine, named after its inventor James B. Francis.
Explanation:
The inward flow reaction turbine is a type of hydraulic turbine used for the generation of electricity. It consists of a wheel or rotor with a series of curved blades or vanes mounted on its periphery. The rotor is connected to a shaft, which is coupled to a generator to produce electricity.
The working principle of an inward flow reaction turbine can be explained in the following steps:
1. Water enters the turbine: The water is supplied to the turbine through a penstock or a pipe. It enters the turbine at the outer periphery of the rotor.
2. Flow direction: As the water enters the turbine, it flows towards the centre of the wheel due to the curved shape of the blades. This inward flow of water is the distinguishing characteristic of an inward flow reaction turbine.
3. Conversion of pressure into kinetic energy: As the water flows towards the centre of the wheel, the shape of the blades causes a pressure drop, converting the potential energy of the water into kinetic energy.
4. Impulse and reaction: The turbine operates on both the impulse and reaction principles. The pressure drop in the blades causes an impulse force, propelling the water and causing the rotor to rotate. Additionally, the curved shape of the blades allows for a change in the direction of the water flow, resulting in a reaction force that further contributes to the rotation of the rotor.
5. Shaft rotation: The rotation of the rotor is transferred to the shaft, which is connected to a generator. As the shaft rotates, it generates electricity through the generator.
Advantages of inward flow reaction turbine:
- High efficiency: Inward flow reaction turbines are known for their high efficiency in converting the energy of flowing water into mechanical energy.
- Wide operating range: These turbines can operate efficiently over a wide range of flow rates and heads, making them suitable for various hydraulic power generation applications.
- Compact design: The compact design of these turbines allows for easy installation in limited space.
In conclusion, an inward flow reaction turbine operates by allowing water to enter the turbine at the outer periphery and then flow towards the centre of the wheel. This design enables efficient conversion of the potential energy of the water into mechanical energy, which can be further utilized for electricity generation.
