- Find the flow rate of water in cm3 /s if the value of soil permeability is 0.9 cm/s, hydraulic gradient is 1.25, and the diameter of the soil specimen is 175 mm.arrow_forwardAnswer in three decimal places pleasearrow_forwardThe section size of a water pipe is (100cm Χ 100cm), three types of soils A, B, and C are placed in the pipe, and a fixed amount of water is injected into the top left tap to keep the water head difference between the left and right ends of the pipe 60cm. The three soil permeability coefficients are k_A = 0.05 cm/sec , K_B = 0.1 cm/sec, k_C = 0.001 cm/sec, please calculate the following values:(1) The fixed amount of water injected into the faucet on the upper left (cm3/hr)(2) What is the total water head consumed by each of the three soils of A, B, and C (cm)(3) The overall volumetric seepage force of water flowing through the three soils (kN/m3)arrow_forward
