In an impulse turbine, steam expands

In a nozzle, the effect of supersaturation is to increase the dryness fraction of steam.

The isentropic enthalpy drop in moving blade is two-third of the isentropic enthalpy drop in fixed blades of a turbine. The degree of reaction will be

The stage efficiency (η_S) is given by (where η_B = Blading efficiency, and η_N = Nozzle efficiency)

The discharge of steam in a convergent-divergent nozzle __________ after the throat (i.e. in the divergent portion of the nozzle)

The impulse reaction turbine has its driving force

The critical pressure ratio for initially dry saturated steam is more as compared to initially wet steam.

The difference of supersaturated temperature and saturation temperature at that pressure is called

When the back pressure of a nozzle is below the designed value of pressure at exit of nozzle, the nozzle is said to be

The variation of steam pressure in the nozzle depends upon

The critical pressure gives the velocity of steam at the throat

The rate of discharge through the nozzle __________ when the exit pressure is gradually reduced.

The efficiency of reaction turbine is maximum when (where α = Angle made by the absolute velocity (V) at inlet)

In a convergent divergent nozzle, the discharge depends upon the initial conditions of steam and the area of nozzle at throat.

In reaction turbines, the axial thrust is due to

The turbine, in which the general direction of the steam flow is parallel to the turbine axis, is called axial flow turbines

The ratio of the workdone on the blades to the energy supplied to the blades, is called

Steam turbines are used for

The Parsons' reaction turbine has

In reaction turbines, the axial thrust is due to

The velocity of steam leaving the nozzle (V) is given by (where K = Nozzle coefficient or nozzle efficiency, and h_d = Enthalpy or heat drop during expansion of steam in a nozzle)
