The flow rate QL of circulating liquid was measured by the heat-pulse method. It was found that QL increased with increasing liquid viscosity. In a h''quid where bubble coalescence was not hindered, the gas holdup in the annulus decreased and therefore QL increased.
Empirical equations for gas holdups in the draught tube and the pressure drop due to flow reversals, necessary for estimating QL, were proposed.
