1.A stream of water of cross-section area A and velocity v1 strikes a plate which moves to the right with a velocity V. Determine the magnitude of V, knowing that A 5 600 mm2, v1 5 30 m/s and P 5 400 N.
2.How can you tell when inductors and capacitors are in series. Say for like a thevenin equivalent how would you add inductors that are in series and parallel. And how would you add conductors in series and parallel. Also if conductors and series are together.
3.A confined auquifer with a porosity of 0.15 is 30 m thick. The potentiometric surface elevations at two observation wells 1000 m apart are 52.35 m and 56.90 m. If the horizontal hydraulic conductivity of the auquifer is 25 m/ day determine the flow rate per unit width of the auquifer.
Show or formulate the shear and bending moment expressions for each board, and plot/draw the shear and bending moment diagrams of the boards.
A block with an inclination of 20 degrees has a weight of 60kg, a height of 1.8m and width 1m, static friction is 0.3, what is the force needed and the height (where the force in the box should be) to pish it upwards
determine the rate of discharge through the gate; b) determine the critical depth , yc at the minimum energy, Es,min; c) determine the critical depth, yc at the current flow; d) determine the alternate depth; e) determine the flow regime (sub- or ..
If the elevation of the pipeline at the treatment plant is 125 m, estimate the pressure in the pipeline 1 km downstream where the elevation if 110 m. Hint: Use the Colebrook equation to estimate f, and the energy equation to estimate P2 .
A tracer dye is injected into a 55-ft thick sandy gravel confined aquifer which has a hydraulic conductivity of 1.2 x 10^-3 ft/s. The dye appears 14 days later in an observation well 75 ft away from the injection point.
A 200 foot long, 2.5 feet in diameter, straight, corrugated metal storm drain pipe, is used to drain a parking lot. The elevation difference between the pipe ends is 8 feet. What velocity would be expected
Determine the minimum force P to prevent a 30kg rod AB from sliding on a wall. The contact surface at B is smooth, whereas the coefficient of static friction between the rod and the wall at A is Us=0.2.
An incident occurs on a freeway that has a capacity in the northbound direction, before the incident, of 4000 veh/h and a constant flow of 2900 veh/h during the morning commute. ( no adjustments to traffic flow result from the incident) at 8:00 am a ..
a beam is made by bonding a brass core to a steel tube and is subjected to a bending moment as shown. knowing that b
The suitcase has a mass of 15kg, and a constant friction of 15N opposes the motion. She starts with an initial speed of 0 and moves the suitcase a distance of 20m. Find the speed of the suitcase at the end of the path.
On this segment of freeway, the directional peak-hour volume is 3800 vehicles with 2% large trucks and 4% buses (no recreational vehicles), the peak-hour factor is 0.90, and all drivers are regular users.
A car travels along a horizontal circular curved road that has aradius of 600 m. If the speed is uniformly increased at a rate of 2000 km/ h2 , determine the magnitude of the acceleration at the instant the speed of the car is 60 km/h.
