It is influenced by soil properties, drainage conditions, and stress levels.\n\nFor 90% consolidation, the time factor (Tv) is approximately 0.56. However, this calculator uses more precise formulas to provide accurate results based on the input values.\n\nThe Travel Distance (d) represents the distance water needs to travel to escape the soil layer, which is crucial for designing drainage systems and estimating settlement times.\n\nCommon Misunderstandings\nThe most common misunderstanding is assuming a constant time factor. The time factor actually varies with the degree of consolidation. For 90% consolidation, Tv is approximately 0.56.\n\nAnother error is using the wrong drainage path. In single drainage, d = H, while in double drainage, d = 2H.\n\nCalculate coefficient of consolidation factor time tv 90 Formula and Explanation\nPrimary Result: Degree of Consolidation (U)\nThis is given as 90% since the calculator is specifically for 90% consolidation.\n\nTime Factor (Tv)\nTv = (π * U²)/4 (for U < 60%)\nWhere:\nU is the degree of consolidation as a decimal\n\nTravel Distance (d)\nd = (2 * H) * √((4 * Tv * cv)/π)\nWhere:\n\nH is the soil layer thickness\ncv is the coefficient of consolidation\nTv is the time factor\nVariables Table\nVariable\tMeaning\tUnit\tTypical Range\ncv\tCoefficient of Consolidation\tcm²/s\t0.0001 - 1\nt\tTime (90% Consolidation)\tseconds\t10,000 - 1,000,000,000\nH\tSoil Layer Thickness\tcm\t10 - 1000\nU\tDegree of Consolidation\t%\t90\nPractical Examples\nExample 1: Clayey Soil in a Construction Site\nProblem:\nA clay layer is 8 cm thick and has a coefficient of consolidation of 0.05 cm Coefficient of Consolidation Calculator (TV 90%)
