• The discharge flow rate Qd for both paddle impeller and pitched blade paddle impeller were measured with the flow follower method. The discharge flow rate number obtained for the paddle impeller Nqd was correlated with the power number Np and the impeller dimensions, based on the correlation form derived from the angular momentum balance between the impeller tip and the vessel wall. The correlation of Nqd obtained for the paddle impeller was modified with the blade angle θ to give the correlation of Nqd for the pitched blade paddle impeller. The resultant correlations were(Nqd)NB = 0.14(D/d)1/2β[(D2H/d3)Np]1/2(3.3γnp0.7bsin1.6θ/H)θ/π<div align="right">for γnp0.7bsin1.6θ/H < 0.3</div>= 0.14(D/d)1/2β[(D2H/d3)Np]1/2<div align="right">for γnp0.7bsin1.6θ/H > 0.3</div>for a non-baffled vessel and(Nqd)B = 0.25(np0.7b/d)–1/4β[(D2H/d3)Np]1/2(2.5γnp0.7bsin1.6θ/H)θ/πfor a baffled vessel, respectively. These correlations reproduced not only the present experimental results but also the results measured by other investigators within ±30% experimental error.
