Explain Why Nozzles are made convergent and Divergent?
Answers were Sorted based on User's Feedback
Answer / soumen sarkar
In the convergent part pressure decreases and hence
velocity increases according to Bernouli's theorem . hence
Nozzles are made convergent .
convergent nozzles are used to get sonic velocity .when
requirement is more than sonic velocity convergent-
divergent nozzle are used,with a little loss due to
sepertation.

Answer / gaurav
nozzels are made convergent divergent for maximum mass flow
rate.
| Is This Answer Correct ? | 13 Yes | 8 No |
Answer / akash patel
in order to increase the velocity of flow of fluid nozzles r made convergent in shape
while where there is necissity to get high pressure of water they r made divergent
| Is This Answer Correct ? | 6 Yes | 2 No |
Answer / amjed
convergent portion will increase velocity. divergent
portions are to reduce losses due to seperation
| Is This Answer Correct ? | 8 Yes | 6 No |
Answer / vivek
as we know when the area decreases the velocity increases
so convergent section are used to increase the velocity
and divergent section are used to reduse the friction losses
| Is This Answer Correct ? | 4 Yes | 2 No |
Answer / bakiyaraj
increase the velocity of fluid or other liquid
| Is This Answer Correct ? | 10 Yes | 9 No |
Answer / arvind yeram
during convergent portion, because of the own inertia of
the fluid it creats venacontracta. to reduce the friction
the divergent portion is provided.
| Is This Answer Correct ? | 3 Yes | 5 No |
Answer / pa srikanth
As we know from pascal law that PV=constant
and we also AV=constant which is volume flow rate so
whenever we are decreasing area at that region velocity
increases and we get required jet velocity
but where as in divergents we increase area decreasing
velocity and finally we get more pressure.
