Momentum flow rate formula
WebUsing this equation, pressure drop ‘∆p’ in the laminar regime across ‘l’ length of the pipe can be easily calculated. To summarize the laminar flow equation: The flow rate is directly proportional to the radius of the pipe. Thus, the small increase in pipe diameter can significantly increase the flow rate in the system. Webthrough the surface, it carries not only mass, but momentum as well. The momentum flow can be described as −→ momentum flow = (mass flow)×(momentum /mass) where the mass flow was defined earlier, and the momentum/mass is simply the velocity vector V~. Therefore −→ momentum flow = ˙mV~ = ρ V~ ·nˆ AV~ = ρV nAV~ where Vn = V ...

Web13 mei 2024 · Substituting the equation for thrust given above: I = S (mdot * Veq) dt . Remember that mdot is the mass flow rate; it is the amount of exhaust mass per time that comes out of the rocket. Assuming the equivalent velocity remains constant with time, we can integrate the equation to get: I = m * Veq . where m is the total mass of the propellant. Web12 apr. 2024 · Xu, Y. Huang, and J.
