    Specific gravity of solids = 2.7)

    First, we need to find the water content at the shrinkage limit. The shrinkage limit is the point at which any further loss of water does not cause any further reduction in volume. At this point, the soil has the minimum volume.

    Let's assume that the dry density of the soil at the shrinkage limit is 17 kN/m3. We can calculate the water content at this point using the following formula:

    Water content = (wet unit weight - dry unit weight) / (dry unit weight - unit weight of solids) x 100%

    Water content = (19 - 17) / (17 - 2.7) x 100% = 40.74%

    So, the water content at the shrinkage limit is 40.74%. Now, we can calculate the shrinkage limit using the following formula:

    Shrinkage limit = (w - ws) / ws x 100%

    where w is the water content at the shrinkage limit and ws is the water content at the fully saturated state.

    Shrinkage limit = (40.74 - 40) / 40 x 100% = 1.85%

    Therefore, the shrinkage limit for the soil sample is 1.85%.
