Navier Stokes Equation describes the motion of fluid substances.
It is a set of equations that describe how the velocity, pressure, temperature, and density of a moving fluid are related.
Named after Claude-Louis Navier and George Gabriel Stokes.
Used in various fields such as aerospace engineering, oceanography, and weather prediction.
Casting is a manufacturing process in which a liquid material is poured into a mold, where it solidifies into the desired shape.
Liquid material is poured into a mold
Material solidifies into desired shape
Common materials used for casting include metals, plastics, and concrete
Free float is the amount of time an activity can be delayed without delaying the project, while total float is the amount of time an activity can be delayed without delaying the successor activities.
Free float is specific to an activity, while total float is calculated across the entire project network.
Free float is calculated by subtracting the early start date of the activity from the early start date of the nex...
Critical path is the longest sequence of tasks in a project that must be completed on time to ensure the project finishes on schedule.
Critical path helps in identifying the minimum amount of time needed to complete a project.
It consists of tasks that have zero slack or float, meaning any delay in these tasks will delay the entire project.
Activities on the critical path are often marked with a double line in projec...
