Ok after hours of contemplating I think I finally understood the concept(hopefully ). However I still need 1 quick clarification.
When water flows suddenly from a larger to a small dimater
Bernoulli says
1. Pressure decreases
2. Velocity of fluid increases
I'll put numbers just for easy understanding
This is according to Bernoulli assuming no loss
Energy in large diameter (Hydrostatic pressure=4 Kinetic energy=2)
Energy in small diameter(Hydrostatic pressure=2 Kinetic energy=4)
Ok in real life when you consider resistance in the smaller tube is it the K.E that is lost to create lower fluid velocity. If hydrostatic pressure is the pressure that exerts on the walls, why isn't that decreased instead. I mean resistance from walls only affect molecules hitting against it which is H.P. I just like to know what type of resistance decreases K.E in real life. Thanks a lot
