your answer. An agitated tank is required to disperse gas in a solution of properties similar to those of water. The tank is 3 m in diameter and a power level of 0.8 kw/m'is chosen. Assume a standard Rushton turbine configuration and fully turbulent conditions. (i)What power is required by the impeller ? (ii)At what speed should the impeller be driven? (iii)If a small pilot scale tank 0.3 m diameter is to be constructed to test the gas dispersion process, at what speed should the impeller be driven ?
