Which of the following is a medium head turbine in which water flows ...
High head turbine: In this type of turbine, the net head varies from 150m to 2000m or even more, and these turbines require a small quantity of water. Example: Pelton wheel turbine.
Medium head turbine: The net head varies from 30m to 150m, and also, these turbines require a moderate quantity of water. Example: Francis turbine.
Low head turbine: The net head is less than 30m, and also, these turbines require a large quantity of water. Example: Kaplan turbine.

Medium Head Radial Inward Flow Turbine
The medium head radial inward flow turbine is a type of turbine used to generate hydroelectric power. It is designed for use in medium head applications, where the water pressure is not too high or too low. The turbine works by allowing water to flow inwards radially, which drives the turbine blades and generates electricity.
Types of Turbines
There are three main types of turbines used in hydroelectric power generation:
1. Pelton Wheel: This turbine is designed for high head applications and uses a jet of water to drive the turbine blades.
2. Francis Turbine: This turbine is designed for medium head applications and uses a combination of radial and axial flow to drive the turbine blades.
3. Kaplan Turbine: This turbine is designed for low head applications and uses axial flow to drive the turbine blades.
Medium Head Radial Inward Flow Turbine
The medium head radial inward flow turbine is a type of Francis turbine that is specifically designed for medium head applications. It is also known as a radial flow turbine because the water flows inwards radially, perpendicular to the axis of rotation. This type of turbine is best suited for applications where the water pressure is between 30 and 300 meters.
Advantages of Medium Head Radial Inward Flow Turbine
There are several advantages to using a medium head radial inward flow turbine, including:
1. Efficient: This type of turbine is highly efficient, with efficiencies ranging from 85% to 90%.
2. Reliable: The design of the turbine is simple and robust, which makes it reliable and easy to maintain.
3. Cost-effective: The turbine is relatively inexpensive to manufacture and install, which makes it a cost-effective option for medium head applications.
Conclusion
In conclusion, the medium head radial inward flow turbine is a type of Francis turbine that is designed for medium head applications. It is efficient, reliable, and cost-effective, making it a popular choice for hydroelectric power generation.
