Webwhere I f is the flow index; ω 1, N 1 are the water content and the number of blows at any point 1 on the flow curve, respectively; and ω 2, N 2 are the water content and number of blows at any point 2 on the flow curve, respectively. Flow index indicates the rate at which a soil mass loses its shear strength with the increase in water ... WebThe following is the procedure for performing the liquid limit test. Arrange the ff. in exact order. 1. Place a soil paste in the cup. 2. A groove is then cut at the center of the soil pat with the standard grooving tool. 3. By the use of the crank-operated cam, the cup is lifted and dropped from a height of 10 mm (0.394 in.).
