A steel storage tank 20m in diameter will be used to hold liquid petroleum product. When filled, the tank causes a bearing pressure of 150kPa. The soil underlying the tank has a unit weight of 16.5kN/m3 above the water table and 19.8kN/m3 below the water table. For a depth of 10m below the base of the tank, compute the effective vertical stress when the tank is empty and when it is full, for points under the center and the edge. (Assume the base of the tank is on the ground surface and ground water table, GWT, is 5m below the ground surface. Ignore the empty weight of the tank).

A spherical storage tank contains oil. The tank has a diameter of 6 feet. You are asked to calculate the height at which an 8-foot-long dipstick would be wet with oil when immersed in the tank when it contains 6 ft3 of oil. The equation giving the height h of the liquid in the spherical tank for the given volume and radius is given by: f(h) = h3−9h2 + 3.8197 Use the secant method to find roots of equations to...

A storage tank contains ethanol. As liquid ethanol is taken from the lower part of the tank, nitrogen is fed into the upper part of the tank so that the pressure above the liquid in the tank is always 780 mmHg. Currently the depth of the liquid ethanol in the tank is 1.2 m. It is a summer day. The temperature in the tank is 50 OC. (a) If you took a sample of the vapor in the tank, what...

A two-phase liquid–vapor mixture of Refrigerant 134a is contained in a 2-ft3, cylindrical storage tank at 100 lbf/in.2 Initially, saturated liquid occupies 1.6 ft3. The valve at the top of the tank develops a leak, allowing saturated vapor to escape slowly. Eventually, the volume of the liquid drops to 0.6 ft3. If the pressure in the tank remains constant, determine (a) the mass of refrigerant that has escaped, in lb, and (b) the heat transfer, in Btu. PLEASE USE THE...

Liquid bismuth flows at a rate of 4.5 kg/s through a 5.0-cm-diameter stainless-steel tube. The bismuth enters at 415oC and is heated to 440oC as it passes through the tube. If a constant heat flux is maintained along the tube and the tube wall is at a temperature 20oC higher than the bismuth bulk temperature, calculate the length of tube required to effect the heat transfer. For liquid bismuth: ? = 1.34 ?10-3 kg/m· s Cp = 0.149 kJ/kg.oC k...
