Flow rate equation cross sectional area
WebIn hydrodynamic, the mass-flow rate can be derived from volume flow rate with help of Continuity Equation. The Continuity equation is given by Q = AV Where, A = Cross sectional Area V = Velocity of flow of fluid Multiplying the continuity equation with density of the fluid we get, m = ρAV Mass flow meter WebSolution: Fluid velocity in joined pipes requires the continuity equation: A_1 v_1=A_2 v_2. A1v1 = A2v2. Since the pipes are cylindrical, each cross-section is a circle with area A=\pi r^2 A = πr2. Additionally, v_2 = 20 \text { m/s} v2 = 20 m/s is given, so \pi r_1^2 v_1 = \pi r_2^2 v_2 πr12v1 = πr22v2

WebPhysics questions and answers. The volume flow rate in an artery that supplies blood to the brain is 3.5*10^-6 m^3/s. If the cross-sectional area of the artery is 8.5*10^-5 m^2, what is the average speed of the blood through this vessel? Find the average blood speed through a narrowed section of the artery where the cross-sectional area is ... Volumetric flow rate can also be defined by: where: • v = flow velocity • A = cross-sectional vector area/surface The above equation is only true for flat, plane cross-sections. In general, including curved surfac…
WebThe mass flow rate is primarily dependent on the cross-sectional area of the nozzle throat and the upstream pressure , and only weakly dependent on the temperature .The rate does not depend on the downstream pressure at all. All other terms are constants that depend only on the composition of the material in the flow.
