SAE 10 oil at 20°C flows between parallel plates 8 mm apart, as in Fig. P4.86. A mercury manometer, with wall pressure taps 1 m apart, registers a 6-cm height,

as shown.Estimate the flow rate of oil for this condition. Hint: Look in the text under the section labeled “Flow due to pressure gradient between two fixed plates.") [-0.003 m³/s*m]
