Steady flow means the velocity pressure and crosssectional a

Steady flow means the velocity, pressure, and cross-sectional area of the conduit may be different values from point to point but they do not change with time. Shear stress in turbulent flow is due to momentum transfer among random moving molecules. Steady-state means uniform flow velocity Comparing laminar and turbulent flows, a laminar flow yields a larger pressure drop. nabla middot V = 0 means irrotational In a section of pipe the fluid flow is uniform (V = 10 feet/sec) and steady (partial differential V/partial differential = 0) therefore, the acceleration equal to zero. nabla times V = 0 means mass is conserved The sum of the components in the Bernoulli Equation is equal to the total pressure along the streamline.
