What is the momentum balance equation?

The momentum balance equation reveals the forces acting on the filament formed in a melt spinning process. The magnitudes of these forces play an important role in determining the structural development, specifically the structural arrangement of the polymeric chains.

What are the applications of momentum equation?

The momentum equation is used to determine the resultant force exerted on the boundaries of a flow passage by a stream of flowing fluid as the flow changes its direction or the magnitude of velocity or both.

What does momentum balance mean?

The momentum balance is related to the mass en velocity of objects in a specific direction, so can be combined with mass and energy balance. In the first chapter you will learn to define the momentum balance.

What is the significance of continuity equation in fluid flows?

The continuity equation describes the transport of some quantities like fluid or gas. The equation explains how a fluid conserves mass in its motion. Many physical phenomena like energy, mass, momentum, natural quantities, and electric charge are conserved using the continuity equations.

What is momentum balance based on which theory law it is formulated why direction is important to make a momentum balance?

Newton’s second law of motion states that the rate of change of a body’s momentum is equal to the net force acting on it. The momentum and position operators are related by the Heisenberg uncertainty principle.

What is the momentum of a fluid?

The momentum of a fluid is defined to be ρu, per unit volume. Newton’s second law of motion states that momentum is conserved by a mechanical system of masses if no forces act on the system.

How is momentum used in engineering?

Momentum is the resistance of an object to a change in its velocity. This lesson deals with how force acting over an extended amount of time changes an object’s momentum. Engineers use this concept to make our lives safer by designing products to lengthen the time over which a deceleration occurs.

What are the principles of momentum?

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.

What is the significance of momentum?

Momentum is important in Physics because it describes the relationship between speed, mass and direction. It also describes the force needed to stop objects and to keep them in motion. It can also predict the speed and direction of motion of objects after collision.

Is the momentum balance equation scalar?

We seek equations for microscopic mass, momentum (and energy) balances that are general. Microscopic mass balance is a scalar equation. Microscopic momentum balance is a vector equation.

What is the physical significance of equation of continuity Mcq?

Explanation: Continuity equation is related to mass conservation. It states that the total mass entering a body is equal to the total mass leaving a body. Mass entering the body = mass leaving the body.

What is the principle behind equation of continuity?

principle of conservation of mass
The equation based on the principle of conservation of mass is called the continuity equation.
