Question

Convert 5 cP to Pa.s and estimate the correct answer.

(a) 0.5

(b) 0.25

(c) 0.05

(d) 0.005

The question was posed to me in final exam.

The question is from Factors Affecting Broth Viscosity topic in section Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

To convert centipoise (cP) to pascal-seconds (Pa·s), use the conversion factor:

1 cP = 0.001 Pa·s.

Therefore:

$5\text{cP}=5\times 0.001\text{Pacdotps}=0.005\text{Pacdotps}$.

The correct answer is:

(d) 0.005
