Water under a gage pressure of 350kPa flows with a velocity of 5 m/s through a right-angled bend that has a uniform diameter of 250 mm. The bend lies in a horizontal plane, and water enters from the west and leaves toward the north. Assuming no drop in pressure, what is the magnitude and direction of the resultant force acting on the bend?
a vertical curve with grade1= 3.6% meets the exit grade of -4.7% at PVI located at station 26.50. A vertical curve of 700 feet is propsed to provide the transition between the two grades.
Using a design speed of 50 mi/h, determine the stations and elevations of PVCs, PVIs, and PVTs of the two vertical curves required to connect the highway segments, as well as the length of the constant grade section (connecting grade is to be as s..
A 20-kg iron ball is moving at 100 km/hr should be accelerated at a constant rate of 10 m/(sec)^2. What is the force required
two forces applied as shown to a hook support. knowing that the magnitude of P is 35 N, determine by trigonometry the required angle if the resultant R of the two forces applied to the support is to be horizontal and the corresponding magnitude of..
find the unknown quantity in each of the following, using the standard series equivalence formulas and tables in the Appendix. Give preference to the approach yielding the fewest computational steps.
The slabs are to be built integrally with the end supports, which are spandrel beams. fy = 60,000 psi, fc' = 4000psi normal-weight concrete. Clear spans are 15 feet, 18 feet and 15 feet. with the longitudal span of 38 feet.
If a unit mass of groundwater accelerates from rest to an average linear velocity of 1 m per year and climbs a vertical distance of 1 m, compare the ratio of kinetic energy to the potential energy of the unit of groundwater.
List the series of steps involved in converting rural land into development. You may refer to an example of local conditions in your reference jurisdiction or you may use a description of such steps that you find from other sources
Find the volume of the solid S. The base of S is the region enclosed by the parabola y=4-3x^(2) and the x-axis. Cross sections perpendicular to the y-axis are squares.
The door of an oven has 27.9lb weight that acts vertically through point D. The door is supported by a hinge at point A and two springs that are symmetrically located on each side of the door.
The piezometers are 280 m apart. The difference in piezometric head bewteen the two is 1.4 m. The aquifer hydraulic conductivity is 50 m/d and the porosity is 20%.
Calculate the total active earth force per foot of wall and its point of application from the base of the wall. Use Rankine theory. Calculate the total active earth force per foot of wall if the angle of wall friction between backfill and wall is 2..
