Flow function equation
Webi.e., the flow of mass m through a surface per unit time t.. The overdot on the m is Newton's notation for a time derivative.Since mass is a scalar quantity, the mass flow rate (the … WebJul 18, 2024 · Stream function. A streamline at time t is defined as the curve whose tangent is everywhere parallel to the velocity vector. With dx along the tangent, we have. u × dx = 0. and with u = (u, v, w) and dx = (dx, dy, dz), the cross product yields the three equations. vdz = wdy, udz = wdx, udy = vdx. or equivalently,

WebNov 5, 2024 · The SI unit of flow rate is m 3 /s, but other rates can be used, such as L/min. Flow rate and velocity are related by Q = Av where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing out of the pipe. WebFinally, since c p = γ c v, we can get. (40) s − s 1 c p = 1 γ log ( T T 1) + γ − 1 2 γ log ( T t − T T t − T 1). Based on given reference state, we can use Equation (40) to construct a Fanno line on a T − s diagram. Let’s do that for a flow where γ = 1.3 in a constant-diameter duct with friction, using a reference Mach number ...
