For the shown inverted manometer, all fluids are at 20°C. If P, - P, = 130 kPa, what must the height y be? Meriam red oil SG = 0.83 0.25 m Water Mercury A SG = 13.6 0.4 m

Please answer and show all of your work.

Question (2): Determine the head in the region between the two materials and the discharge in cm³/sec for the following sketch. Y Area=34 cm² K=0.03 cm/sec H Area=34 cm² K=0.004 cm/sec

A constant head permeameter has a cross-sectional area of 175 cm2 and is used to measure the hydraulic conductivity of a field sample 40 cm long. If the permeameter discharges 100 ml in 320 seconds under a head difference of 60 cm. a. What is the hydraulic conductivity as measured in the laboratory? b. What is the intrinsic permeability of the sample given that water at 20 C is used for the test? c. Is Darcy's law valid under the given conditions (D = 50 mm)? d. What would be the in situ hydraulic conductivity if the regional groundwater temperature is 12 C
