Soil Mechanics and Foundation Due to a rise in temperature, the viscosity and the unit weight of the percolating fluid are reduced to 60% and 90% respectively. If other things remain constant, the coefficient of permeability increases by 50% increases by 25% increases by 33.3% decreases by 33.3% increases by 50% increases by 25% increases by 33.3% decreases by 33.3% ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation If the water table rises upto ground surface, then the effective stress is reduced due to increase in pore water pressure only but total stress does not change total stress is reduced due to increase in pore water pressure only but effective stress does not change total stress is increased due to decrease in pore water pressure but effective stress does not change effective stress is reduced due to decrease in total stress only but pore water pressure does not change effective stress is reduced due to increase in pore water pressure only but total stress does not change total stress is reduced due to increase in pore water pressure only but effective stress does not change total stress is increased due to decrease in pore water pressure but effective stress does not change effective stress is reduced due to decrease in total stress only but pore water pressure does not change ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation Clay layer A with single drainage and coefficient of consolidation Cv takes 6 months to achieve 50% consolidation. The time taken by clay layer B of the same thickness with double drainage and coefficient of consolidation Cv/2 to achieve the same degree of consolidation is 24 months 6 months 3 months 12 months 24 months 6 months 3 months 12 months ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation Degree of consolidation is directly proportional to drainage path and inversely proportional to time directly proportional to time and inversely proportional to drainage path directly proportional to square of drainage path and inversely proportional to time directly proportional to time and inversely proportional to square of drainage path directly proportional to drainage path and inversely proportional to time directly proportional to time and inversely proportional to drainage path directly proportional to square of drainage path and inversely proportional to time directly proportional to time and inversely proportional to square of drainage path ANSWER DOWNLOAD EXAMIANS APP
