WebOct 10, 2015 · One way to answer it is to start from what Reynolds number means physically: it represents the ratio between "typical" inertia forces and viscous forces in the flow field. So, you look at a typical flow pattern, and choose the best length measurement to represent that ratio of forces.
WebWhat is the smallest orifice that can be used? (Hint: Calculate the Reynolds number through the pipe. The Reynolds number through the pipe must be great than this because D 2 < D 1 ⎝ ⎛ R e 2 = μ ρ (v 1 D 2 2 D 1 2 ) D 2 = μ ρ v 1 D 2 D 1 2 ⎠ ⎞ .. . This should help with the coefficient of discharge even if the actual velocity is not ... WebApr 10, 2024 · Reynolds number is a dimensionless quantity that is used to check whether the type of flow pattern is laminar or turbulent while flowing through a pipe. It is defined as the ratio of the inertia force to the viscous force. The Reynolds number equation is Re = (ρ * u * L)/μ or Re = (u * L)/v Where, Re is the Reynolds number
WebThe mean velocity of fluid flow can be calculated as follows: In the case where the desired mean velocity of the fluid flow is known as well as the required volume flow through the pipe, the inner diameter of the pipe can be calculated according to the following: where is: D - internal pipe diameter; q - volumetric flow rate; v - velocity; A ... WebAn orifice with diameter D2 = 50 mm is inserted in a 4" Sch 40 steel pipe with inside diameter D1 = 102 mm. The diameter ratio can be calculated to d = (50 mm) / (102 mm) = 0.49 From the table above the discharge coefficient can be estimated to approximately 0.6 for a wide range of the Reynolds number.
