A cylindrical soil sample, 7.3 cm in diameter and 16.8 cm long, is tested in a Constant Head Permeability Apparatus. A constant head of 75 cm is maintained during the test. After 1 min of testing, a total of 945.7 g of water was collected. The temperature was 200C, and the void ratio (e) of the soil was 0.43. Calculate the "Coefficient of Permeability" in "centimeters per second" (Given, k = (QL)÷(A Δh t)).
The gate is rectangular with a horizontal width of 2m perpendicular to the paper. For a depth h = 3m of water, calculate the required force exerted by the hydraulic cylinder to keep the gate just closed.
What is your recommendation for the maximum size of coarse aggregate for the following situation?
Plot variation with depth from the top to Point C for σ' v and σ h when the soil is at rest and Estimate the undrained shear strength (c u ) of clay. (Assume the shear strengths to be 200 kPa and 2 kPa at Liquidity Index (IL) values of 0 and 1, res..
Find the expanded depth of the bed after the backwash when initial depth of the bed is 3 ft using given conditions. μ = 0.01g/cm/sec, T = 25oC, ρs = 2.65, ρ=1, washrate = 1.5 cm/sec, ks2 = 196. (Assumed single size)
A 2000-lb wheel load is to be supported by aggregate over soil with a maximum bearing pressure of 1000 lb/sqft. What depth of aggregate is needed if the angle theta is 40 degrees?
what is the probability that the vehicle pulling out will get in an accident with oncoming traffic?
How do you find the force ratio equation to determine the maximum total load that can be applied to a truss?
Compute the maximum acceptable tensile service load T that may act on a single angle L6x4x3/4 that is welded along only one leg to a gusset plate; thus, there are no holes. The service load is three times the dead load. Solve for a0 A36 steel.
If the BOD5 of the river below the mill outfall must not exceed 5 mg/L, what percent removal of organic matter (BOD5) is required by the mill to meet this requirement?
A constant head permeability test was conducted on a clean sand sample. The diameter and length of the test specimen were 10 cm and 12 cm respectively.
Select the sentence that is punctuated correctly.
For a mixed liquor volatile suspended solids (MLVSS) of 1800 mg/L, what is the total return solids flow rate?
