A stirred-tank reactor is to be scaled down from 10 m3 to 0.1 m3. The dimensions of the large tank are: Dt = 2 m; Di = 0.5 m; N = 100 rpm. What would be the required rotational speed of the impeller in the small tank if impeller Re number is constant?

Consider a 1000-l CSTR in which biomass is being produced with glucose as the substrate. The microbial system follows a Monod relationship withn µ_m = 0.4 h^-1 , K_S = 1.5 g/l (an unusu ally high value), and the yield factor Y_X/S = 0.5 g biomass/g substrate consumed. If normal operation is with a sterile feed containing 10 g/l glucose at a rate of 100 l/h. What is the specific biomass production rate (g/l-h) at steady state?
