A clay lense of Kc=0.10cm/day is sandwiched somewhere inside a vertical soil column of height 100cm that is otherwise filled withsand of Ks=200cm/day. A depth of water d=10cm is ponded above the surface.
a. If the actual flux rate is Jw = -15cm/day, how thick is the claylense?
b. Calculate the pressure at the clay-sand interface for two cases:1) clay on top of the sand and 2) clay on the bottom of thevertical sand column.
Suppose that a water treatment plant has a Parshall Flume with a 4 ft wide throat. a) If the upstream depth of the water (ha) is 1 ft and the depth of the water in the throat section (hb) is 0.65 ft, what is the flow rate in gpm
Assume the beam is 2" x 10" in cross section. Calculate the bending stress distribution that is present at the base of the cantilever and at every 2.5 ft increment toward the free end of the beam
A beam that is part of a rigid frame has end moments and mid-span moments for dead, live, and earthquake loads. Determine the governing load combination for both negative and positive moments at the ends and mid-span of the beam.
This causes the student to begin to rotate. Find the student's final angular velocity. The moments of inertia of the wheel and of the student are 0.313 kg · m2 and 2.09 kg · m2 respectively.
Saturated liquid water at 1.0 MPa is throttled adiabatically to a pressure of 0.4 MPa. If the change is kinetic energy is negligible, what percentage of the water evaporates during this throttling process?
Determine the force at the circular endcap and its location relative to the bottom of the pipe. If there is a hinge at the bottom, what external force would need to be applied to the top to prevent rotation
Swimmer A immediately starts walking toward B at a speed of 2ft/s relative to the raft. Knowing that the raft weighs 300 lb, determine (a) the speed of the raft if B does not move, (b) the speed with which B must walk toward A
The canal shown below is to be widened so that it can carry twice the amount of water. Determine the additional width L required if all other parameters (i.e. flow depth, bottom slope, surface material, side slope) are to remain the same.
A 30 lb uniform cylinder can roll without sliding on a 15 degree incline. A belt is attached to the rim of the cylinder, and a spring holds the cylinder at rest. If the center of the cylinder is moved 2 in.
Draw the S.F.D and B.M.D for the beam as a single unit and determine the position and amount of hte maximum bending unit. 5kN 30kN 5kN A B C D E 2m width 2.5m width 2.5m width 2m width 20kN 20kN
Point F is located just to the left of the 18kN and 25 kN*m couple moment. A) Determine the internal normal force at point E in the compound beam. B) Determine the shear force at point E in the compound beam.
The portable floor crane in the automotive shop is lifting a 420 lb engine. For the position compute the magnitude of the force supported by the pin at C and the oil pressure p against the 2.70 in. diameter piston of the hydraulic cylinder unit AB..
