1. (10 points) A field sample of an aquifer 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°C. If the estimated hydraulic conductivity of the sample is 30 m/day, calculate (A) the hydraulic gradient along the cylinder: h: 160cm 스.em, yA ,333 mm ? r. (B) the total volumetric discharge (flow rate): KIA 교 -프(D. IQ 4.5 dau (C) the specific discharge: D45 349,65 m a , с 1131-3991 (D) the average linear flow velocity: (E) Could this apparatus be used to test another field sample having a hydraulic conductivity of 86.4 m/day and a median grain diameter of 5 mm? Use the Reynolds number of I as the criterion for the Darcy's law to be applicable.
