... considered the case of constant viscosity flow. However, gradients in the effective viscosity can occur normal to the wall for the flow of lubricating oils, and for turbulent flows calculated using an eddy viscosity model. In this paper the effect of these viscosity gradients on the stagnation point pressure...

... F 2 due to reflection from the face of the piston ( 11 ). Using the relationship given above for the calibration of the KP-136 hydrophone, the maximum dynamic tension sustained by degassed, deionized water at 20°C was found to be 90 bar ( ± 5 bar ) . lubricating oils...
