Convergent-divergent nozzle in steam engineering

Question

Why convergent-divergent  Nozzle increase the velocity of steam

Sangram Ghadge · Answer

At the inlet mach no. is less than 1, while at throat it is eual to 1.At the divergent portion, mach no. is greater than 1 which implies that the velocity of steam at divergence is increased.

Prem Kumar Das · Answer

In inlet portion(convergent)pressure of steam is high but velocity is low because the the of area of convergent portion is continuously decreased ,this phenomenon is reciprocal in the side of divergent... So convergent divergent nozzle increase the velocity of steam....

Shubhanshu Sahu · Answer

The vel. Of steam increase in convergent side so that mach no.  Increase divergent side act as a nozzle

Rohit Kumar · Answer

The main use of a steam nozzle in steam turbines which produces ajet of steam with a high velocity

Vasudevan T · Answer

Pressure at the exit of the C-D nozzle is always lower than the intake and thus the velocity of flow at the exit will be higher

Moturu Praveen Bhargav · Answer

because the pressure is gradually decreasing. as the pressure decreases the velocity increases..

Kompelli Srikanth · Answer

As we know,  Pressure is inversely proportional to the Area.At throat the area is small  then  pressure increases because of increasing in pressure the force of outcoming steam increases
