Draw the phreatic surface for the earth dam shown in Figure P14.7. Determine the flow rate within the dam if k = kx = 1 ×10-6 cm/s.
What point defects are possible for MgO as an impurity in Al2O3. How many Mg2+ ions must be added to form each of these defects.
Design a rectangular channel contraction from width b1 (upstream) to width b2 (downstream). Assume uniform flow approaches the contraction (i.e. normal depth approaching the channel contraction).
A ten-foot high wall will retain a medium dense sand backfill. Determine the Rankine earth pressure diagram and the total active force on the wall.
To satisfy desige limitation it is necessary to determine the effect of the 2- kN tension in the cable on the shear tension and bending of the fixed I-beam.
In an oedometer test, the void ratio of a clay sample changed from 1.62 to 1.41 as the vertical effective stress imposed on the sample was increased from 100 kPa to 200 kPa.
A block of material A is placed in closed contact with unlimited supply of material B, after 15 hours at temperature T1, it is observed that atoms of B have penetrated 0.5mm into material A.
n ideal gas in 1.50 gallon container is at a temperature of 125 degrees Celsius and of 2.5 atmospheres. If the gas is oxygen (formula: O_2, molecular weight = 32 grams per mole), what is the amount of gas in the container in units of grams
Because of the insulation between them, the sun heats up the wall panel 120 degrees F but the column to 80 degrees F. Determine the consequent compressive stress in the curtain wall.
If the average velocities in the 0.15 m and 0.2 m diameter pipes are 2 m/s and 3 m/s respectively, then find the average velocity in the 0.3 m diameter pipe
And forms HCN, it will volatilize, and if it volatilizes, HCN can poison mine workers. At pH 10.4, what fraction of the cyanide is in the CN- form?
A bar is under uniform axial loads. AB is 1 foot and has a area of .5 in^2 and BC is 1 foot and has an area of .3 in^2. AB has a 1000lb force putting it under tension and BC has a 500lb force putting it under compression. Find stresses in AB and BC a..
A 12-in well is drilled through a confined aquifer of average thickness 80 ft. Two observation wells located 50 and 120 ft away register a difference in drawdown of 10 ft. The steady-state pumping rate is 1000 gpm
