An aquifer having a thickness of 4 m, has a hydraulic conductivity of 2 x 104 m/s. Two piezometers have been installed at points A and B at a distance of 850 m. apart horizontally. Elevation of the water surfaces at A and B are at elevations 120.32 m. and 122.64 m. respectively. a) Compute the hydraulic gredient. b) Compute the transmissivity in m²/day. c) Compute the flow rate in the aquifer per unit width in liters/day.
