2. Examples of mixing plant calculations

Determine the geometrical and operating characteristics of a stirrer capable of homogenizing a viscoelastic rheofluidifying pasty medium in a 0.8 m ³ reactor in 10 min, and keeping it isothermal. Extrapolation of this operation to a 12 m ³ reactor.

Properties of the pasty medium at process temperature: ρ = 1,000 kg · m ^-3 ; λ = 0.6 W · m ^-1 · K ^-1 ; c _p = 4,180 J · kg ^-1...
