# Flow through Convergent-Divergent Duct

 P: 2 Guys, i would like to ask some opinion from u all. About the convergent-divergent duct, it is horizontal flow and the water is incompressible. So, based on Bernoulli's equations, elevation and density is the same. Because of the frictional losses, the actual total pressure head, H is less than then the Ideal Pressure Head. Any disagreement from you guys, or any other opinion. If the convergent-divergent duct is inclined upward, what will happen???
 P: 53 If the duct was inclined upwards the pressure head will increase at the upstream due to difference in height , but the total head loss will stay constant . The flow will continue until the pressure head at upstream equals the elevation head at downstream thus velocity head will be zero and the fluid comes to rest.
 P: 2 Guys, Following the quesrtion by neostalker, I would like to know what would happen if the flow is with compressible fluids ? What will be pressure loss in this case ?

Given the generality of your question, here is a good point to start reading:
