A chemical tracer is pumped into an aquifer at well A. The tracer is then detectedin water samples at well B in 2years, which is located 1.5km away. This experiment provides an estimate of the actual velocity of the fluid as is migrates through the pore spaces of the porous medium. The average head level at each well is shown in the figure, and the aquifer is known to have a hydraulic conductivity of 10-4m/s. Calculate the porosity of the porous medium.
