# What is the Degree of Reaction for Parson’s Reaction Turbine?

## Introduction to Parson’s Reaction Turbine

The Parson’s Reaction Turbine is one of the most popular and commonly used turbines for generating electricity. It is a type of reaction turbine, meaning that it uses the reaction forces created by the pressure of the water to create a rotating motion. This rotating motion is then used to drive the blades of the turbine and generate electricity.

## What is the Degree of Reaction?

The degree of reaction is an important factor in determining the efficiency of any reaction turbine. It is a measure of how much of the energy of the water flow is used to drive the turbine blades. A higher degree of reaction means that more of the kinetic energy of the water is converted into mechanical energy, thus increasing the efficiency of the turbine.

## Calculating the Degree of Reaction

The degree of reaction for a Parson’s Reaction Turbine can be calculated by dividing the total pressure drop across the turbine by the total head of the water flow. The total pressure drop is the difference between the pressure of the water entering and leaving the turbine. The total head is the difference between the maximum pressure of the water and the atmospheric pressure.

## Optimizing the Degree of Reaction

The degree of reaction for a Parson’s Reaction Turbine can be optimized by adjusting the design of the turbine blades. The blades should be designed to make maximum use of the kinetic energy of the water flow. This can be done by altering the shape and angle of the blades to make them more efficient at capturing the energy of the water flow.

### Conclusion

The degree of reaction is an important factor in determining the efficiency of any reaction turbine, and the Parson’s Reaction Turbine is no exception. By optimizing the design of the turbine blades, the degree of reaction can be increased and the efficiency of the turbine improved.
