(d) 15µm diameter water droplet in air.
(3)
Centrifugation can be used to isolate non-spherical colloidal proteins from milk.
(a) Under the centrifuge conditions listed below, two distinct proteins can be
isolated at T=293K. Determine the mass per protein for each set of data, assuming
each protein has a density of 1.4g/cm³ (or 1400kg/m³ in SI units).
D
Protein 1
1.0x10$^{-12}$ m²/sec
Protein 2
2.8x10$^{-12}$ m²/sec
S
2200x10$^{-13}$ sec
(5 minutes @ 5,000rpm)
800x10$^{-13}$ sec
(40 minutes @ 20,000rpm)
(b) Use your answer from part (a) to determine the ratio, $f_f/f_i$, for the heavier of the
two proteins.
(4)
Derive equation #54 on p. 88 of Hiemenz and Rajagopalan.
