WebMar 5, 2024 · The discharge through this pipe is regulated by a control valve and can be measured using a measuring cylinder [7]. The flow velocity, therefore, can be determined to calculate Reynolds number. ... The Reynolds experiment determines the critical Reynolds number for pipe flow at which laminar flow (Re<2000 ) becomes transitional … WebJun 24, 2024 · The Reynolds number is the ratio of the inertia forces to the viscous forces and is given by: Re = V * rho * l / mu. ... It is observed experimentally that a roughened cylinder or ball will transition to turbulent flow at a lower Reynolds number than a smooth cylinder or ball. Drag for a rough surface ball is shown on the figure at the top of ...

Compressible flow past a heated circular cylinder at subcritical Reynolds number of 3900 is numerically investigated by using the large-eddy ... WebThe value of the critical Reynolds number is different for different geometries. For flow over a flat plate, the generally accepted value of the critical Reynolds number is Rex ~ 500000 . For flow in a pipe of diameter D, experimental observations show that for “fully developed” flow, laminar flow occurs when ReD < 2300, and turbulent flow ...
