A 40-cm straight pipe is used to carry water at 20 degrees C from resevoir A to resevoir B that is 0.7 km away. There is an elevation difference of 9-m between the two resevoirs. Determine the discharge for (a) commercial steel (b) cast iron (c) smooth concrete and the flow gain if the highest capacity pipe material is chosen over the lowest.
Construction dewatering plays are very large role in the todays construction arena. Discuss the role water conditions plays in the planning and design of a temporary earth support system.
You fill a 2 cubic foot wheelbarrow to the top with aggregate. If the specific gravity of the aggregate is 2.548 and 18% of the aggregate is void spaces, how much does the aggregate in the wheelbarrow weigh
A copper wire breaks under an engineering stress of 43x10^3 psi. Its ductility is 77%it reduction area. Calculate the true stress (in psi) for fracture in the neck region.
After removal from the oven, its unit weight is 109 lb/ft3. Compute the void ratio, porosity, initial moisture content, and a specific gravity of the soil, assuming its volume did not change during the drying process.
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
The car's position is defined by the position vector, where . The image below shows the system projected onto the x-y plane. What are the car's velocity and acceleration vectors at this position
Draw A flow net. Show flow lines, flow Channels, and Equipotential lines. Using flow nets, please provide an estimate of seepage rate below the dam. Your submittal will provide the basis for an environmental impact statement regarding the construc..
The volume and the average density of an irregularly shaped body are to be determined by using a spring scale. The body weighs 7200 N in air and 4790N in water. Determine the volume and density of the body.
what is the uniform deterministic arrival rate if the vehicle queue is cleared in 35 minutes after vehicles begin to arrive (in veh/min.)?
A geological fault truncates the aquifer at a distance "L" upstream from the river. The hydraulic conductivity of the area between the fault and the river is 50 ft / day and hydraulic conductivity between the lake and the fault is 100 ft / day.
Assume for your calculations that each member is in tension, and include in your response the sign of each force that you obtain by applying this assumption.
consider a spacecraft that is positioned directly between the earth and moon.the mass of the moon's is approximately 7.35 X10^22 kg, and at the instant under consideration, the moon is 3.8 X 10^8 km from earth.
