Flow momentum

WebThe expression of momentum is a function made up of two terms: The momentum of flow passing through a channel section per unit time per unit weight of water and the second is the force per unit weight of water. The sum is known as Specific Force: zbar = distance from the water surface to the centroid of the cross sectional area of flow. WebAug 9, 2024 · So then, our equation reduces to this, summation f is equal to m., V2 minus V1. Which, again, I can write as rho Q V2 minus V1, where Q is the volume flow rate and the mass flow rate is equal to rho times Q. So this is the final form of the Momentum Theorem, probably the most common way that we'll be using it in the FE exam.

WebPhysically, the linear momentum equation states that the sum of all forces applied on the control volume is equal to the sum of the rate of change of momentum inside the control volume and the net flux of momentum through the control surface. For steady flow, the first term on the right hand side vanishes. WebConsider some basic unit analysis. Pressure is defined as force/area which is the same as momentum/area/time since F=dp/dt.
