Hello everyone
I have a simple question regarding how to calculate the speed of a fluid in a normal pipe with a constant cross-section
If we are given the pressure difference at the two ends of the pipe (P1 and P2) is it possible to calculate the speed of the fluid? (I think I can imagine this problem like an inflated balloon attached to a little pipe)
Using Bernoulli’s equation:
P1/rho+V1^2/2= P2/rho+V2^2/2
Since the channel cross-section “A” does not change we have:
Rho*A*V1= Rho*A*V2 --> V1=V2
Therefore
P1=P2 !?Am I doing something wrong? Should I use another formula or in a different order?Thanks in advance for your helpDara
