2. Two formations, each 25 m thick, overlie one another. If a constant-velocity vertical flow field is set up across the set of formations with h = 120 m at the top and h = 100 m at the bottom, calculate h at the internal boundary. The hydraulic conductivity of the top formation is 0.0001 m/s and of the bottom formation 0.0010 m/s. Plot head vs. depth. Is the gradient constant, or does it change at the boundary between formations? Why must the gradient be larger in the unit with lower conductivity?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
