Dear Rahul, Raj Sahu is correct, in equal conditions, when pressure is increasing, the velosity is increasing too. You must careful read about the theme in Aerodynamic or Hydrodynamic courses.

With best regards David Babayan

Back to the basics: the Bernoulli' principle is known since nearly 3 centuries. Read on wiki about it: http://en.wikipedia.org/wiki/Bernoilli_equation . The whole discussion can be reduced to reading this famous equation:

Clearly, if the "input pressure" po increases, the "output velocity" v will increase. However, when the section of a pipe enlarges, the velocity v will decrease and the static pressure p will increase.

Even without the equation, it is clear that -for example- compressed air will flow faster if its pressure is higher.

Dear Mr Sahu

Greeting.............................

Thnx for your concious coverage, but i will kind to have graph which is drawn between nozzle prssure and tip velocity.
