: Lines that are tangent to the velocity vector at every point in the flow field. Types of Flow :
: Flow in conduits where there is a free surface exposed to atmospheric pressure (e.g., rivers, canals). Recommended Study Resources Mehanika fluida - handout
: Unlike solids, fluids deform continuously under shear stress and do not return to their original shape. Density ( ) : The mass per unit volume ( Viscosity ( : Lines that are tangent to the velocity
Fluid mechanics is a branch of physics that studies the laws of equilibrium and flow of fluids (liquids and gases). Density ( ) : The mass per unit
: An extension of Bernoulli's equation to account for energy losses (friction) and energy gains (pumps). 5. Flow in Pipes and Channels Reynolds Number (
: Energy lost due to friction against pipe walls, often calculated using the Darcy-Weisbach equation .
: Smooth, layered flow versus chaotic, mixing flow. Equation of Continuity : Based on the conservation of mass ( for incompressible fluids). 4. Fluid Dynamics (Hidrodinamika) Examines the relationship between forces and fluid motion.
