Two wells are drilled 710 m apart in a confined aquifer with a thickness of 42 m. The heads in the upgradient and downgradient wells are measured at 68.4 and 57.2 m, respectively. The valley in which the aquifer is located is 1.4 km wide. The aquifer's hydraulic conductivity is 24 m/d, and its effective porosity is 0.22. Find the volumetric flow rate Q, specific discharge q, and velocity v of the water flowing through the aquifer.
