What Are The Disadvantages Of Velocity Compounding?

1.	What Are The Disadvantages Of Velocity Compounding?
Answer» Steam velocity is too high and that is responsible for APPRECIABLE FRICTION losses. Blade EFFICIENCY decreases with the increase of the number of stages. With the increase of the number of rows, the POWER developed in successive rows of blade decreases. For as MUCH as, the same space and material are required for each stage, it means, therefore, that all stages are not economically efficient. Steam velocity is too high and that is responsible for appreciable friction losses. Blade efficiency decreases with the increase of the number of stages.
