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
i just wanted to ask that what should one do to clear all
the concepts a mechanical engineer needs to have
cleared,this not only includes the concepts of each and
every semester of his engineering course, but also the
basic laws and fundamentals of physics(that required for
Mechanical engineering).I am a third year mechanical
engineering student and i am very keen to know about the
above question. somebody please help me.
