water flows from a lake into a steep natural channel. the water surface elevation of the lake is 97.0 with respect to the datum. the channel properties are given below. determine the flow rate in the channel
Water, initially dry saturated vapour at 4 bar, lls a closed rigid con- tainer. The water is heated until its temperature is 400C. Determine the work done and the heat transfer.
The motion is described by the second Newton's law: m(d^2y/dt^2) + a(dy/dt) + ky = 0 where y is the body displacement in m, t is the time in s, a > 0 is the friction coeffcient in kg/s and k is the spring constant in kg/s2.
The soil properties are Cc = 0.4, Cr = 0.1 and fsat = 18 kN/m3 for both clays, and the water table is 1 m below the soil surface. Determine the settlements when a stress of 60 kPa is applied by the building.
A light bar AD is suspended from cableS and supports a 20 kg block at C. The extremities A and D of the bar are in contact with frictionless, vertical walls. Determine the tension in cable BE and the reactions A and D
The footing is supported to carry a net safe load of 400 kN/m^2 with FS = 3. Given Ysat = 20.85 KN/m^3 and phi = 35 degrees, find the required width of the footing using Terzaghi's general shear failure criterion.
Two towers A and B are located on flat ground and their bases have equal elevations above sea level. A person on tower A whose eye level is 26.0 ft above the ground can just see the top of tower B, which is 105 ft above the ground. How far apart a..
