WebbOverview. The OPTISENS PH 8300 is a pH sensor for industrial or municipal wastewater, surface or process water applications. The glass sensor is equipped with a dirt-repellent PTFE diaphragm, making it particularly suitable for harsh applications. It is available with optional integrated Pt100 for temperature compensation. WebbGiven a potentiometric surface with a regional slope of 7 m/km, calculate the natural rate of groundwater discharge through a confined aquifer with transmissivity, T = 0.002 m 2 /s. Show by dimensional analysis on the equation that the storativity is dimensionless. A horizontal aquifer is overlain by 50 ft of saturated clay.
