For gas-liquid dispersions in agitated vessels, the gas flow rate \(Q_{\mathrm{G}}\) is also important. Show that an additional group, namely the flow number defined as \(Q_{\mathrm{G}} /\left(\Omega d_{\mathrm{I}}^{3}\right)\) is needed in order to correlate the data. Hence the power number is then correlated as a function of the Reynolds number and the flow number. Search the literature and find the common correlations suggested for this.
