This discussion focuses on the conversion of vacuum pressure measured in mbars to the equivalent centrifugal force measured in "g's" for filtration processes. The user seeks assistance in equating the pressure from a vacuum system to the force required by a centrifuge. The mathematical relationship established is Dm*a*g = DP*A, where Dm represents the density difference between the solution and air, a*g is the acceleration of the centrifuge (notably at 100g's), DP is the pressure drop in the vacuum system, and A is the area of the filter. This formula provides a clear method for calculating the necessary parameters for transitioning from vacuum filtration to centrifugation.
PREREQUISITESThis discussion is beneficial for chemical engineers, laboratory technicians, and researchers involved in filtration processes, particularly those transitioning from vacuum systems to centrifugation methods.
dsch said:I've been using a vacuum system to filter solutions. I would like to move it over to a centrifuge. I have been having trouble equating the pressure in the vacuum to the required amount of force required by a centrifuge. Can someone help me out with the math? I'm looking a the vacuum pressure in mbars and for centrifugation, it seems that standard gravity is best (number of "g's").
