A strip footing, 5 m wide, is founded on the surface of a deep deposit of clay. The undrained shear strength of the clay increases linearly from 3 kPa at the surface to 10 kPa at a depth of 5 m. Estimate the vertical ultimate load assuming that the load is applied at an eccentricity of 0.5 m right from the center of the footing's width. (Hint: Try a circular failure surface, determine the equation for the distribution of shear strength with depth, and integrate the shear strength over the radius to find the shear force.)
Calculate the Air flow required in CFM to transfer 5,396 BTU/Hour in an HVAC duct given that the temperature difference (Delta-T) between the room and the supply air is 21 DegF.
Besides irrotation incompressible flow, list 3 physical processes governed by Laplace equation. (feel free to list more, they're a bonus)
Everyone has experienced using a water fountain that produces a bit too much water pressure. In fact, the drinking fountain on the 3rd floor of Dana Hall at the south end of the hallway shoots a pretty good jet of water
find principle stresses, max shear stress at a cross section 2 ft from the left of each locations: a) neutral axis, b) 2in. above neutral axis, c) the top of the beam.
A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -30°C by rejecting its waste heat to cooling water that enters the condenser at 18°C at a rate of 0.25 kg/s and leaves at 26°C.
The "U"-tube manometer containing mercury of density 13600 kg/cubic meters is used to measure the pressure drop along a horizontal pipe.
A 600 MW power plant has an efficiency of 36 percent with 15 percent of the waste heat being released to the atmosphere as stack heat and the other 85 percent taken away in the cooling water. Instead of drawing water from a river, heating it, and ret..
At a confining pressure of 2000 psi, the first sample failed at 9000 psi. Then at a confining pressure of 5000 psi, the other sample failed at 21,000 psi. Plot the two test results on a shear stress-normal stress diagram and draw in Mohr envelope.
If the BOD5 of a municipal wastewater is 310 mg/L and the BOD U is 340 mg/L, determine the BOD reaction rate constant (base e). What would be the 3 day 30°C BOD Assume, temperature coefficient = 1.047.
