A swing-type laboratory centrifuge with the following characteristics Medium Radius: (R1+R2)/2=10cm Sedimentation distance: R1-R2=12cm The filtration time in the laboratory is 4 min. In the laboratory, the suspension is centrifuged at 1,200 rpm. The laboratory centrifuge is used to characterize a plant centrifuge, whose sigma value is 1,200 ml. Calculate the flow rate it can treat. The yeast sedimentation characteristics are 1.05 g/ml, and the particles (yeasts) are approximately 10 cm in diameter. The exhausted broth has properties equal to those of water
