सघनण परीक्षण (consolidation test) में, जब मृदा के नमूने पर भार 150 kN/m2 से बढ़ाकर 200 kN/m2 किया जाता है, तो रिक्ति अनुपात (void ratio) 0.60 से बदलकर 0.55 हो जाता है। आयतन संपीड्यता गुणांक (mv) की गणना करें।

A soil yields a maximum dry density of 1.6 g/cm3 at an optimum moisture content (OMC) of 18% during a standard Proctor test. If the specific gravity G = 2.62, find the void ratio and degree of saturation.

A stratified soil deposit consists of three layers with permeabilities k1 = k, k2 = 2k, and k3 = 3k, and thickness values H1 = h, H2 = 2h, and H3 = 3h respectively. Find the ratio of equivalent permeability in the horizontal direction to that in the vertical direction (kH / kV).
