Abstract

with the value obtained from the slope in where a is a function of ionic diffusion coefficient, C 0 is the capacitance of the diffused layer at the point of zero charge, z is the valance, k is Boltzman's constant, e 0 is the electron charge, and T is the absolute temperature. This correction brings the agreement between theory and experiments to better than 20 percent. In other words, it improves the agreement by a factor of 5. Since the ultimate scope of this work is to produce an instantaneous pressure measuring system in liquids with a variable dependence as given in equation Conclusions In conclusion, it has been shown that the physical model of Stern gives an analysis for the fluctuating electric potential of an electrode in good agreement with the experiments. The system is one that provides a method of measurements of fluctuating local flow pressures in a liquid and with a very small time con- Hydrodynamic Entry Length for Laminar
