Theoretical flow formula
WebbFor flow adjacent to a hot or cold surface, T b is the temperature of the fluid "far" from the surface. For boiling or condensation, T b is the saturation temperature of the fluid. For flow in a pipe, T b is the average temperature measured at a particular crosssection of the pipe. WebbThe drag equation = is essentially a statement that the drag force on any object is proportional to the density of the fluid and proportional to the square of the relative flow …

Webb8 aug. 2024 · The force necessary to move a plane of area A past another in a fluid is given by Equation 2.2.1 where V is the velocity of the liquid, Y is the separation between planes, and η is the dynamic viscosity. (2.2.1) F = η A V Y V/Y also represents the velocity gradient (sometimes referred to as shear rate). Webb7 feb. 2024 · We can calculate the flow through a valve using the following formula. Q = C v Δ P S G. Suppose we use water with a specific gravity of 1.0 and a constant for the Cv. We can see that, as the pressure delta (pressure difference in the upstream and downstream sides of the valve) increases, so does the flow.
