Impulse Turbine: If the energy available is only kinetic energy at the inlet of the turbine, the turbine is known as an impulse turbine. e.g., a Pelton wheel turbine.
Reaction Turbine: If at the inlet of the turbine, the water possesses kinetic energy and pressure energy, the turbine is known as a reaction turbine. e.g., e Francis and Kaplan turbine.
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 periphery to the centre (centripetal type); Example: old Francis turbine
Outward flow turbine: The flow is outward from the centre to periphery (centrifugal type); Example: Fourneyron turbine
Axial flow turbine: The flow of water is in the direction parallel to the axis of the shaft. Example: Kaplan turbine and propeller turbine
∴ Francis turbine is a radial inward flowing reaction turbine.

Pelton turbine is an impulse flow turbine
Pelton turbine is a type of hydraulic turbine used in hydroelectric power plants. It is designed to convert the potential energy of water into mechanical energy, which can be further converted to electrical energy. Pelton turbine is classified as an impulse flow turbine because it works on the principle of impulse force, which is generated by the high-speed water jet striking the buckets of the turbine.
Working principle of Pelton turbine
The working principle of Pelton turbine is based on the following steps:
1. Water is stored in a reservoir at a certain height.
2. The water is then allowed to flow through a penstock, which is a pipeline that carries water to the turbine.
3. The water is then directed towards the Pelton wheel, which has a series of buckets or cups attached to its rim.
4. The water jet strikes the buckets of the wheel, generating an impulse force that causes the wheel to rotate.
5. The rotation of the Pelton wheel is then transferred to a generator, which converts the mechanical energy into electrical energy.
Advantages of Pelton turbine
Pelton turbine has several advantages over other types of hydraulic turbines, including:
1. High efficiency: Pelton turbine has a high efficiency of up to 90%, which means that it can convert a large amount of water into mechanical energy, resulting in higher power output.
2. Low maintenance: Pelton turbine has a simple design, which makes it easy to maintain and repair. It also has fewer moving parts, which reduces the risk of mechanical failure.
3. Wide range of applications: Pelton turbine can be used in a wide range of applications, from small-scale hydroelectric power plants to large-scale power plants.
Conclusion
In conclusion, Pelton turbine is an impulse flow turbine that is widely used in hydroelectric power plants. It works on the principle of impulse force generated by the high-speed water jet striking the buckets of the turbine. Pelton turbine has several advantages over other types of hydraulic turbines, including high efficiency, low maintenance, and a wide range of applications.
