Deriving the equation for S* for competitive product inhibition.

Problem Statement: Derive the equation for S* for competitive product inhibiton. Definition of variables: S* = the surface substrate concentration at steady state. (For plug flow reactor); Sb = bulk substrate conc; Ks = mass transfer coeff; Ki = competitive inhibition rate constant; Km = substrate conc that give 1/2 max enzyme reaction rate; Vmax = max specific growth rate; V= specific growth rate;

Calculating the Maximum Volume of Fermentor that can be used without Additional Cooling

The heat generated by fermentor is 60 kcal/hr L. The cooling capacity of jacket is 10,000 kcal/hr m^2. For a cylindrical fermentor with H/D of 3, the jacket area (m^2) is porportional to fermentor volume (m^3) to the 2/3 power. Area of Jacket (m^2) = 7*v^(2/3) (m^3) What is the maximum volume of the fermentor that can be used without additional cooling capacity?
