Measurements are reported of pressure losses across single screens subjected to low-frequency oscillating flow for where is Reynolds number based on wire diameter and peak approach velocity. Several correlation methods are examined. Extensive comparisons are made between present oscillating-flow results and previous reports of the resistance of screens to steady flow. Defining oscillating results in terms of peak amplitudes, the oscillating and steady-flow resistances are found to be the same, including behavior in the intermediate Reynolds number region that departs from correlations of the form The friction factor is also found to depend on Reynolds number, but not independently on oscillation amplitude, over the range of conditions measured.
