The factors, examined at three levels, included: pH, oil concentration, feed flow velocity, and temperature.
The effect of four process parameters, namely pH, bed height, oil concentration and flow velocity on the removal efficiency of the resin bed were studied simultaneously.
The analyses of oil droplet movement, mass and momentum transfer during the impingement of droplet/wall, as well as wall oil film thickness and flow velocity are very important for the bearing chamber lubrication and heat transfer calculation.
By applying a large flow loop, we conducted the experiment that the above three species of bacteria attached to the coupons were scoured by diesel oil at three different flow velocity (1.3 m/s, 1.5 m/s and 3 m/s).
The dependence of the differential pressure drop Δp and the level of internal oil saturation S on the flow velocity of the air were investigated experimentally for a typical oil mist filter composed of oleophilic glass microfiber layers.
The effects of different parameters including membrane type (regenerated cellulose and polysulphone), transmembrane pressure (TMP), the content of oil in the feed, the flow velocity of the feed and pH on the ultrafiltration of an emulsion of kerosene in water were studied.
Using Darcy's law for oil and water flow, velocities can be expressed as follows: V_{text{o}} = frac{{2pi K_{text{o}} hleft( {P_{text{e}} - P_{text{wf}} } right)}}{{mu_{text{o}} ln left( {{{r_{text{e}} } mathord{left/ {vphantom {{r_{text{e}} } {r_{text{w}} }}} right.
The jet velocity and the oil flow rate have great effects on the average oil volume fraction inside the bearing rather than the oil volume fraction distribution around the circumference.
