The tank has an inner diameter of 1.5 m and a wall thickness of 18 mm. If the pressure in the tank is p=1.20MPa, determine the force in the 16 bolts that are used to attach the cap to the tank. Also, specify the state of stress in the wall of the ..
The thickness of geonet is 0.2 inch (5 mm). Assume the maximum inflow rate is 0.14 inch/hour. The liquid head over the geomembrane liner is 2 inches. The index properties of the soil placed over the geotextile are as follows
After the Chernobyl accident, the concentration of 137Cs in milk was proportional to the concentration of 137Cs in the glass that cow consumed. The concentration in the grass was, in turn, proportional to the concentration in the soil.
