According to Bernoulli eq Pressure of a fluid in a vertical pipe is lower where area is small.But from General formula P=F/A.Pressure should be higher.Isnt it a contradiction?
andytinker said:Some fluids have minimal compression, like water. Two vertical pipes joined at the bottom with one smaller than the other would have movement.
It would be if F were a constant. In Bernoulli's equation it is the fluid flow that is constant, not the forcemoatasim23 said:According to Bernoulli eq Pressure of a fluid in a vertical pipe is lower where area is small.But from General formula P=F/A.Pressure should be higher.Isnt it a contradiction?

andytinker said:With minimal compression, the fluid doesn't follow PV=P1V1. If you have flow from a small section to large the pressure is lower, if its a compressible fluid that gets changed to velocity F=mv2, if its not velocity slows down.
I think
