## Y Pressure Decreases n Velocity increases in a Convergent Nozzle?

friend, i have a doubt...........
in a convergent Nozzle, pressure decreases n Velocity increases. If Velocity Increases, Its Accelaration also increases. So, Force also increases. So, Pressure has to be increased...... But y it is decreasing?

We are converting pressure energy in to velocity (Kinetic) energy, aren't we? So one must decrease. Besides in a convergent divergent nozzle there are 2 portions. About which one are you talking about?
Are you sure? This action cannot be undone.

I need a mathematical relation how pressure is reduced?

go thru Bernoulli's euation (<a href="https://en.wikipedia.org/wiki/Bernoulli's_principle" target="_blank" rel="nofollow noopener noreferrer">Bernoulli's Principle</a>).
This is all about conservation of energy.. if one component increases, other should reduce.

frm boyel's law velocity and acceleration r inversly proportional
