In a BOD test using 5% dilution of the sample (15 ML of sample and 285 mL of dilution water), dissolved oxygen values for the sample and dilution water blank bottles after five days incubation at 20Â°C were 3.80 and 8.80 mg/L. respectively. Dissolved oxygen originally present in the undiluted sample was 0.80 mg/L. The 5-day 20Â°C BOD of the sample is
A footing 2 m x 1 m exerts a uniform pressure of 150 kN/m 2 on the soil. Assuming a load dispersion of 2 vertical to 1 horizontal the average vertical stress (kN/m 2 ) at 1.0 m below the footing is
Two completely penetrating wells are located L (in metres) apart, in homogeneous confined aquifer. The drawdown measured at the mid point between the two wells (at a distance of 0.5 L from both the wells) is 2.0 m when only the first well is being pumped at the steady rate of Q 1 m 3 /sec. When both the wells are being pumped at identical steady rate of Q 2 m 3 /sec, the drawdown measured at the same location is 8, 0 m. It may be assumed that the drawdown at the wells always remains at 10.0 m when being pumped and the radius of influence is larger than 0.5 L Q 1 / Q 2 is equal to
