The expansion process of steam through a nozzle can be approximated to
Consider the following statements:
1. De Laval nozzle is a subsonic nozzle.
2. Supersonic nozzle is a converging passage.
3. Subsonic diffuser is a diverging passage.
Q. Which of these statements is/are correct?
Under ideal conditions, the velocity of steam at the outlet of a nozzle for a heat drop of 900 kJ/kg will be approximately
The effect of friction on flow of steam through a nozzle is to
Because of sonic and supersonic speeds, the time taken by steam for its passage through nozzle is of the order of
The expansion of steam through a nozzle is so rapid that steam may not get time to condense and may remain in a state of homogeneous vapour. The expansion process is then stated to be
