[ introduction ]. From water distribution networks to the veins and arteries in our bodies, pipe networks can evolve into complex architectures. When we consider viscosity in conduit flows, we must be able to quantify the losses in the flow. 87-351 Fluid Mechanics. [ physical interpretation: what are we doing today? ]. The magnitude of these losses will vary significantly depending on many factors, including whether the flow is laminar or turbulent. EFD Final Project. Terrence Hess. Daniel Alexander. Mohammad Khan.

This shows turbulence because it’s all over the place and rough. This part of the picture shows Laminar Flow because it runs very smoothly. Law of conservation of mass. Where, . Mi = input mass of materials. Mo = output mass of materials. If Mi and Mo are different then there are four possible explanation:-. (i) measurement of Mi and Mo may be different. 1.

Most real flows in engineering applications are turbulent. . Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. Momentum is a quantity defined as the product of the mass and velocity of an object.. Unit of Momentum. The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.. What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.
