where [??]XX is the percentile travel time (e.g., TT10, TT50, and TT90); [[lambda].sub.1] is the critical transition flow; [[lambda].sub.2] is the critical capacity flow; [[alpha].sub.1], [[alpha].sub.2], [[gamma].sub.1], and [[beta].sub.1] are parameters.
NPH launched its enhanced shared service model in 2015, and its components include strategic growth and technology support, robust training opportunities and a systematic transition flow process.
The intersections (circles) of the wire-to-water efficiency curves (solid curve) represent the optimal transition flows of the optimal wire-to-water efficiency sequencing control and the intersections (squares) of the pump efficiency curves (dash curves) represent the transition flow rates of the best pump efficiency sequencing control.
The flow regimes of a stepped spillway can be divided into nappe flow, transition flow, and skimming flow [8-10].
(5) Transition flow near the enhanced region boundaries (Interporosity flow between the enhanced region and unstimulated region): In this region, the permeability of enhanced region is higher than that of the unstimulated region.
And they took drag coefficient as 0.2 and extended the application scope of the Turner model to transition flow and turbulence flow (2 x [10.sup.5] [less than or equal to] Re [less than or equal to] [10.sup.6]).
In their study they recommended different Nu-correlation for each inlet configuration under laminar, turbulent and transition flow conditions.
The 3,100 square metre skate park is designed with street elements, obstacles and transition flow areas such as hubbas, pole jams, up-down rails, and soft-ended walls.

For the first condition, comparing CFD results with the experimental data, the following was found: (i) areas in the center of the pipe in the CFD results show that droplets are present in the gas phase indicating annular flow, or that this phase is sufficiently unstable and liquid slugs can break showing a a characteristic of transition flow. (ii) The experimental results show that the gas phase is concentrated in the in the center of the tube and the liquid film is concentrated near the pipe wall, which may indicate that the Taylor bubble travels down the center, characterizing a slug or transition flow.
The permeate fluxes and [Mg.sup.2+] rejections of the membrane were determined for laminar flow, transition flow, and turbulent flow under pressure of 0.35 MPa at temperature of 35[degrees]C.
Linking all knee points at different flow velocities to a curve can obtain a transition flow curve, as shown in Figure 3.
