A coaxial capacitive sensor is desired to measure the water level in a water tank. The coaxial sensor with a length of d=32 cm has an inner radius of a=9 mm and an outer radius of b=12 mm. Since the total capacitor value is measured at the sensor output 4.03 nF, the water level l =? Calculate (Note: It is known that the water temperature in the tank is 20 degrees. The variation graph of the relative dielectric constant with temperature is also given below.)
