When the cross-section of a nozzle __________ continuously from entrance to exit, it is called a convergent nozzle.

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.

In a Parson's turbine stage, blade velocity is 320 m/s at the mean radius and rotor blade exit angle is 30°. For minimum kinetic energy of the steam leaving the stage, the steam velocity at the exit of the rotor will be

The effect of friction in the nozzle __________ dryness fraction of steam.

In a reaction turbine when the degree of reaction is zero, then there is
