1.	For the pelleting of the microsomal fraction from a liver homogenate, an ultracentrifuge is operated at a speed of 40000 rpm. What is the angular velocity, ω, in radians per second?(a) 3888.8 rad s^-1(b) 5680.8 rad s^-1(c) 4188.8 rad s^-1(d) 4288.8 rad s^-1I got this question in exam.My enquiry is from Centrifugation in division Unit Operations of Bioprocess Engineering
Answer» Correct ANSWER is (c) 4188.8 rad s^-1 The best explanation: The angular VELOCITY, ω, may be calculated USING the equation: ω = (2 π REV min-1)/60 ω = 2 × 3.1416 × 40000/60 rad s^-1 = 4188.8 rad s^-1.
