Repeat Exercise 14.2 using the finite difference method.
Exercise 14.2
A sheet pile wall supporting 6 m of water is shown in Figure P14.2.
(a) Draw the flow net.
(b) Determine the flow rate if k = 0.0019 cm/s.
(c) Determine the pore water pressure distributions on the upstream and downstream faces of the wall. (d) Would piping occur if e = 0.55?
The wheel is rolling to the left without a constant angular velocity without slipping. determine the direction of acceleration at point a?
During an engine test on the ground, a propeller thrust T = 4000 N is generated on the 1500 kg airplane with mass center at G. The main wheels at B are locked and do not skid; the small tail wheel at A has no brake.
Assuming a gage reading in the approach well(haa) of 13 ft, select a Parshall flume capable ofmeasuring a flow of 700 ft/s without submerging the flow.
A 5-micron droplet of water is being carried in standard air toward a 500-micron drop of water at a relative velocity of 40m/s. Will the two drops collide
find principle stresses, max shear stress at a cross section 2 ft from the left of each locations: a) neutral axis, b) 2in. above neutral axis, c) the top of the beam.
An unknown fluid flows through a horizontal 35-mm-diameter pipe with a Reynolds number of 100,000 and a density of 680 kg/m3. The pressure drop across a 21-mm-diameter nozzle meter placed in the pipe is 4.2 kPa.
One issue is to calculate the "pooled" variance and "pooled" standard deviation. Since we expect that the variances of the improvement scores by both groups could be a bit different, we'd want an overall value that reflects the variance of both gr..
A hydraulic jump occurs in an rectangular channel 2.3 m wide when the discharge is 2.5 m^3/s. If the upstream depth is 0.25 m calculate the depth downstream of the jump and the energy loss in the jump.
What is the difference between universal beam and universal column steel sections in terms of performance in bending
A saturated soil has a unit weight of 120 pcf and a water content of 32.5%. Determine the void ratio and specific gravity of the soil.
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
The center post B of the assembly has an original length of 124.7mm, whereas posts A and C have a length of 125mm. If the caps on the top and bottom can be considered rigid
