A sample of blood is placed in a centrifuge of radius 10.0 cm. The mass of a red blood cell is 3.0 10-16 kg, and the size of the force acting on it as it settles out of the plasma is 4.0 10-11 N. At how many revolutions per second should the centrifuge be operated?
rev/s Answers: R: revolutions/sec
r: radius of the centrifuge
m: mass of RBC
a = v^2/r
v = (2*pi*r*R)
F on RBC to settle = F on RBC by the fuge
4E-11 = ma
