Bacterial cells were centrifuged using 5 cm long centrifuge tubes in a laboratory centrifuge having an angled rotor which held the tubes at 60 degree angle with the axis of rotation. The top of the tubes were 5 cm away from the axis and it took 15 minutes at a rotation speed of 10,000 rpm to completely sediment the cells. Calculate the sedimentation coefficient of the cells.

Step 1
First, we need to find the angular velocity (ω) of the centrifuge in radians per second. We know that the rotation speed is 10,000 rpm (revolutions per minute). To convert this to radians per second, we can use the following conversion factors: 1 revolution = 2π Show more…

The centrifugal separation of the biomass of 80μm-sized cells of density 1.04 kg/m³ was carried out in a tubular centrifuge having a diameter of 15 cm and rotating at 1200 rpm. Calculate the residence time if the distance between the liquid surface and the axis of rotation was 0.8 cm, the liquid density and viscosity were 1.0 kg/m³ and 0.013 g/cm-s respectively. What would be the volumetric capacity of the centrifuge if its length was 40 cm? Calculate the Σ factor. What will be the time required for centrifuging 1000 liters of broth?

Sedimentation Basin Design – Consider an ideal rectangular sedimentation tank for removing spherical particles from water. The fluid velocity is uniform and horizontal throughout the settling region. Below are physical data for the tank and particles: Height of Settling Zone (H) = 3.5 meters Width of Settling Zone (W) = 6.0 meters Water flow rate through tank (Q) = 0.20 m³/sec Particle Density (ρ) = 2.65 x 10³ kg/m³ Calculate the minimum length of the tank (m) that would remove 40 micrometer diameter particles with 100 percent efficiency. Assume that laminar flow regime applies (16 pts).
