"Web6 sep. 2013 · When you divide the volume of media by the volume of water flow, you get time in minutes. A flowrate of 3 gpm/ft 3 then translates to 3/7.5 = 0.4 ft 3 of water/min. If that is passing through one cubic foot of media, we have a flow of 0.4 ft 3 /min/ft 3 of media for an EBCT of 2.5 minutes. " - Hydrodynamic volume definition

WebPlatelets and red cells are analyzed by a hydrodynamic focusing system, which eliminates potential errors of coincidence, recirculation, and stress changes associated with traditional methods of analysis. This results in more accurate platelet and red cell counts and sizing, even when cell counts are low or high. In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, …

WebThe effective hydrodynamic radii also depend on temperature; for example, the extrapolated viscometric radius of raffinose is 6.4 /k at 0°C, 6.1 ~ at 25°C, and 5.8/k at 50°C (14). Two points are to be noted. First, the decrease in the effective hydrodynamic radii with increasing temperature is consistent
