WebFeb 2, 2011 · The degree of reaction of stages at the mean diameter is usually chosen depending on the relative blade length 1/D (D is the mean diameter of the flow passage) so that ρ r ≥ 0.05 to 0.1 at the blade root. In multistage turbines, the degree of reaction at the mean diameter gradually increases from the first to the last stage. As explained earlier a reaction turbine is one in which there is pressure and velocity loss in the moving blades. The moving blades have a converging steam nozzle. Hence when the steam passes over the fixed blades, it expands with decrease in steam pressure and increase in kinetic energy.
