الحصول على السعر· In the mean, the WVT method estimates a residence time that is days longer than that based on the traditional calculation (note that each curve is associated with its own axis). The amplitude of the annual cycle of the residence time is larger for the WVT calculation, and greater interannual variability is apparent.
الحصول على السعر· For example, if a oneminute residence time is used as a baseline on the oneliter mill, the flow rate would be about half the volume of the mill per minute (based on volume taken up by beads). So, theoretically, a 500liter mill would give about 250 liters per minute flow rate with a direct scale up.
