he pressure of water at a depth of 10 km in the ocean is measured to be 100 MN/m2. The specific weight of the sea water at the surface is 10.2 kN/m3 while the average bulk modulus is 2.4 x 106 kN/m2. Calculate a) Change in specific volume (dV) between the volume at surface and at the 10 km depth. [4] b) The specific volume [3] c) Specific weight of the sea water at 10 km

A descending grade of 4.2% intersects an ascending grade of 3% at sta. 12+325 at elevation 14.2 m. These two grades are to be connected by a 260 m vertical parabolic curve. A reinforced concrete culvert pipe is to be constructed with its top 30 cm below the subgrade (or the lowest point of the curve)
What will be the invert elevation of the culvert?
