Fully developed flow is a state where the velocity profile of a fluid remains constant over time and distance.

• Fully developed flow occurs in long pipes where the fluid has enough time to reach a steady state.

• In this state, the velocity profile is parabolic and the flow is laminar.

• The Reynolds number is used to determine if the flow is fully developed or not.

• Mathematically, fully developed flow is described by the Hagen-Poiseuille equation.

• The Hagen-Poiseuille equation relates...read more

Speed reduction in industrial applications

• Speed reduction is achieved using gearboxes or pulleys and belts

• Gearboxes are used for high torque applications

• Pulleys and belts are used for low torque applications

• Variable frequency drives (VFDs) can also be used for speed control

• Examples include conveyor belts, fans, pumps, and mixers

Navier-Stokes equation is a mathematical formula that describes the motion of fluids.

• It is used to predict the velocity and pressure distribution of fluids in motion.

• It is a set of partial differential equations that describe the conservation of mass, momentum, and energy.

• It is widely used in engineering and physics to study fluid dynamics.

• It is named after Claude-Louis Navier and George Gabriel Stokes, who first derived the equation in the 19th century.

• The equation is diffic...read more
