Derivation of Degree of Reaction in english | Impulse reaction turbine | Thermal engineering
In this video i discussed derivation of Degree of reaction will be 50% of the impulse reaction turbine. Also discuessed about the concept of person's turbine and
discuessed velocity triangle for an impulse reaction turbine represents the relationship between absolute, relative, and blade velocities as steam or fluid interacts with the blade in an impulse turbine. This diagram is crucial for analyzing the efficiency and performance of the turbine stage. It typically consists of the following components:

1. Absolute Velocity (V): The velocity of the fluid relative to the stationary observer. It has an inlet and an outlet component
2. Blade Velocity (vb): The velocity of the moving blade itself.
3. Relative Velocity (Vr): The velocity of the fluid relative to the moving blade. It has an inlet and an outlet component.
4. Angles
Inlet blade angle and outlet blade angle.
1. Relative Velocity at Blade Inlet and Outlet:

2. Work Done Per Unit Mass Flow (Blade work

3. Blade Efficiency or diagram efficiently

4. Energy Supplied (Change in kinetic energy.
