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.
