P please elaborate more...with the spring as eg.

U can see that in the equation u have written...the pressure energy (P) and potential energy (ro*g*h) are the same...isnt it?...really confused

In Bernoulli equation we use pressure energy... Pressure* volume gives the unit of energy... But what does this mean... If someone says it is potential energy per unit volume, then what does datum head refers to?... Please help... Can't go ahead without having thorough knowledge about this..

I saw someone saying that " if velocity of liquid molecules increases then they will have less time to collide with the walls and so pressure decreases " ... Is this correct... It seems to be logical...

Pressure is defined as force per unit area..(i.e) the average force exerted by liquid molecules on the surface of the pipe per unit area... If i reduce the area then there should be more collisions and hence pressure should increase...

We know that pressure= force/area... If the area of the pipe is reduced then the pressure must increase... But according to Bernoulli's, the pressure will decrease ... How is it?
