The efficiency of an impulse turbine is maximum when (where Vb = Blade speed, V = Absolute velocity of steam entering the blade, and α = Nozzle angle)
The expansion of steam in a nozzle follows
In a 50% reaction turbine stage, tangential component of absolute velocity at rotor inlet is 537 m/s and the blade velocity is 454 m/s. The power output in kW of steam will be
The stage efficiency is the ratio of energy supplied to the blades per kg of steam to the total energy supplied per stage per kg of steam.
The pressure compounded impulse turbine as compared to velocity compounded turbine require __________ number of stages.
When the inlet pressure of steam is equal to the exit pressure, then
In an impulse reaction turbine, the pressure drops gradually and continuously over
The expansion of steam, as it flows over the blades in reaction turbine, represents
In pressure compounding of an impulse turbine, the total pressure drop of the steam does not take place in the first nozzle ring, but is divided equally among all the nozzle rings.
The process of draining steam from the turbine, at certain points during its expansion and using this steam for heating the feed water in feed water heaters and then supplying it to the boiler is known as
