A river is 6m deep. The riverbed material has a saturated unit weight of 19.5kN/m3. What is the effective vertical stress 12m below the water surface?
Assume the water is static and assume a datum at the water surface.
A) what is the total head 5.0m below the river bed?
B) What is the pore water pressure at that level?
List the densities in solid, liquid and gaseous state. Also compare the densities for each of them and calculate the density it will have in any ideal gas state.
Determine the the max weight of the block that the system does not fail if the max tension that can be developed in cable DB is 100N and the max compression that can be developed in tower CD is 100N.
Laboratory analysis methodology to be used. Give details on the standard methods, instrument and detection limits. Standard methods for heavy metals analysis exist
A concrete mix witha 3-inch slump, w/c rtion of .5, ans sand with a fineness modulus of 2.4 contains 1700 lb/yd^3 of coarse aggregate. compute the required weight of coarse aggregate per cubic yard.
A froth flotation process is used to concentrate copper ore. It is a two stage process with a rougher stage followed by a cleaner stage. The cleaner tailings are returned to the rougher flotation.
ferryboat queuing lane holds 40 vehicles. If vehicles are processed (tolls collected) at a uniform deterministic rate of 5 vehicles per minute and processing begins when the lane reaches capacity
given a 22.414 liter volume of air at STP containg: 21.224kPa oxygen, 79.119 kPa nitrrogen, 0.946kPa argon,and 0.036 k carbondioxide. Find the gram molecular weight of the air.
a soil sample is obtained by pushing a 16 in long tube into the side of a pit. the tube has an inside diameter of 3 in. and weighs 1.8 lb. The soil in the tube is trimmed so that its ends are flush with the ends of the tube.
How to determine maximum positive and maximum negative factored design moments at a certain point
A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.
A photograph is taken of a transverse wave travelling along a length of rope. At this instant the shape of the wave is described by y = (2 m) sin ((0.8 rad.m-1)x+0.8 rad). The speed of the wave is 2 m/s. Calculate the distance between two successi..
