How do you read the units in tables in Geankoplis when there is a multiplier given in the table heading? For example, how do you read viscosity in Geankoplis' Table A.204 on page 855? Answer. Geankoplis uses the method that you equate the value in the table with the heading above the column. Thus, the viscosity of water at 20^oC is (1.0050 = Pa s 10³⁾, i.e. the viscosity of water at 20^oC is 1 X 10^-3 Pa s.
