Websteady, low feed flow rate (approximately 1/10th that of batch TFF). For example, a feed volume of 0.3 L/m2 running at a feed flow rate of 0.5 L/min/m2 would yield a residence time of approximately 35 seconds. At lower feed flow rates (<0.5 L/min/m2) the residence time would be greater and correspondingly result in higher WebQuestion: Hollow Fibers: Shear (sec-1) = function (velocity, cross-sectional area, flow rate) HE Shear Rate Calculation ShearRate = 1.7x109x( 2 ) = 8000xv/D ^(NxD37 T = ShearRate …
