Both μrho⁢ d and dp⁢ u⁢ rhoμ are dimensionless groups; kg is a coefficient that expresses the rate at which a particular species transfers from the gas to the solid particles; and the coefficients 2.00 and 0.600 are dimensionless constants obtained by fitting experimental data covering a wide range of values of the equation variables. estimate the values of kg for the following data; pay attention to units
