In industries titanium is hardened through diffusion of carbon. The concentration of carbon at 1mm into the surface of the titanium slab is 0.25kg/m³ and at 3mm the concentration is 0.68kg/m³. The rate at which the carbon is entering into its surface is 1.27*10-9kg/m².s. calculate the value of diffusion coefficient of carbon.

Pseudomonas sp. has a mass doubling time of 2.4 h when grown
on acetate. The saturation constant using this substrate is 1.3 g/l (which is
unusually high), and cell yield on acetate is 0.46 g cell/g acetate. If we
operate a chemostat on a feed stream containing 38 g/l acetate, find the
Substrate concentration when the dilution rate is 0.8Dmax?
