Q. For a steady state incompressible flow through a closed conduit uniform cross section , the direction of flow will always be

A

From higher to lower elevation

B

From higher to lower pressure

C

From higher to lower velocity

D

From higher to lower piezometric head

Solution:

All fluids are compressible, their density will change as pressure changes.
Under steady conditions, and provided that the changes in pressure are small and it is incompressible and has constant density.
Hence, the direction of flow for steady incompressible flow through a closed conduit of uniform cross section will always be from higher to lower pressure.
