For an offshere project, a steel pipe pile with an outside diameter of $18 \mathrm{in}$. penetrates $150 \mathrm{ft}$ through sormally consolidated clays. Soil conditions are as follows: From zero to $50 \mathrm{ft}$ depth, the cohesion is 800 pof and the saturated soil unit weight is 105 pef: from 50 to $100 \mathrm{ft}$ depth the cohesion is 1,500 psf and the saturated unit weight is 115 pef, below $100 \mathrm{ft}$, the cohesion is 2,400 paf and the saturated unit weight is $125 \mathrm{pef}$. The water surface is above the soil surface. Using the lambda method, detemmine the axial capocity of the pile in kips, using a factor of safety of 2.
