Please help me solve

Determine the allowable load for a steel closed-ended 
pipe pile, 0.4 m in diameter, driven 20 m into the soil 
profi le shown in Figure P13.5. Groundwater is at 2 m 
below the surface, but you can assume it will rise to 
the surface. A factor of safety of 2 is required. Neglect 
negative skin friction.
