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...read more

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 deriv...read more

Material balance is a concept used in chemical engineering to track the flow of materials through a process.

• It involves accounting for all the inputs and outputs of a system

• It is used to ensure that the process is operating efficiently and effectively

• It can be used to identify areas where losses are occurring and to optimize the process

• Examples include tracking the flow of raw materials into a chemical plant and the fl...read more
