A field sample of an aguifer is packed in a test cylinder. The cylinder has a length of 120 cm and a diameter of 12 cm. The field sample with a porosity of 0.24 is tested under a constant head difference of 160 cm with water at 10 degree Celcius. If the stimated hydraulic conductivity of the sample is 30 m/day, calculate;
Average flow rate and hydraulic gradient.
