A soil sample was consolidated under a cell pressure of 8 kg/cm2, pore water pressure of 4.5 kg/cm2. With no drainage permitted the cell pressure was raised to 10 kg/cm2 results in increased pore water pressure to 5.75 kg/cm2. The axial load was then increased to give a deviator stress of 6.25 kg/cm2 (with the cell pressure at 10 kg/cm2), pore pressure is now noted to be 7.15 kg/cm2. The ratio of pore pressure coefficients B to A is ______.
