Plot the soil profile of Problem 7-15 and the total, neutral, and effective stresses with depth.
Problem 7-15
Soil borings made at a site near Chicago indicate that the top 6 m is a loose sand and miscellaneous fill, with the ground water table at 3 m below the ground surface. Below this is a fairly soft blue-gray silty clay with an average water content of 30%. The boring was terminated at 16 m below the ground surface when a fairly stiff silty clay was encountered. Make reasonable assumptions as to soil properties and calculate the total, neutral, and effective stresses at 3,6, II, and 16 in below the ground surface.
2. Often, the properties of multiphase alloys may be approximated by the relationship ferrite form? (b) How many kilograms of eutectoid ferrite E 1alloy2 = EaVa + EbVb (9.24) form?
Finding the volume of hydrogen, A hydrogen filled balloon of the type used in cosmic ray studies is to be expanded to its full size which is a 100-ft diameter sphere, without stress in the wall at an altitude of 150,000 ft.
a particular manufacturer of charcoal briquettes is contracted to create a product that contains no more than 0.1 mass
Water is contained in a 0.2 m3 vessel at 200 C. The mass of water in the vessel is measured to be 2 kg. Determine (a) the pressure in the vessel, (b) the enthalpy, h, of the water in kJ/kg, (c) the mass and volume of vapor in the vessel.
a well-insulated heat exchanger is used to heat water cp 4.18 kjkgk from 300 k to 90degc with a mass flow rate of 3
air in an internal-combustion engine has 227degc 1000 kpa with a volume of 0.l m3. combustion heats it to 1500 k in a
Estimate (a) the wing span, (b) the aspect ratio, and (c) the induced drag. Take density of air to be 0.7 Kg/m3. Assume that the factors for induced drag and the lift slope, d and t, respectively, are equal to 0.01; i.e., d = t = 0.01.

A uniform linear charge density of 4 nC/m is distributed along the entire x axis. Consider a spherical (radius = 5 cm) surface centered on the origin. Determine the electric flux through this surface.
A five-cylinder, 3.5-liter SI engine operates on a four-stroke cycle at 2500 RPM. At this condition, the mechanical efficiency of the engine is 62% and 1000 J of indicated work are produced each cycle in each cylinder.
Pentane (C5H12) burns with air so that a fraction x of the carbon is converted to CO2. The remaining carbon appears as CO. There is no free O2 in the products. Develop plots of the air-fuel ratio and the percent of theoretical air versus x, for x ran..
