Impact‐static‐shielded tubes were found to be suitable for measuring time‐average velocities in the jet stream flow generated by the marine propeller. Pumping capacities and entrainment flow were then calculated from these velocity profiles. Pumping capacities were correlated by: Q = KpND3. When the tank contained water: Kp = 0.54. The same probe was found to be useful in evaluating qualitatively the flow patterns from turbine and paddle type impellers. The effect of several parameters on the flow patterns are reported.
