A cylindrical soil sample fails under an axial vertical stress of 160 kN/m^2, when it is laterally unconfined. The failure plane makes an angle of 50 degrees with the horizontal. Calculate the value of cohesion and the angle of internal friction of the soil.
The flow depth and velocity before the jumo are 0.8 m and 7 m/s respectively. The flow depth and velocity after the jump are 2.46 m and 2.28 m/s respectivly. Assuming a flat channel, determine a) the energy loss due to the jump, hl (head loss)
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
A 12kw (shaft output) motor is available to run a non-cooled compresor for helium. The pressure is to be increaded from 80 kPa to 120 kPa. If the compressor is 70% efficent, calculate the volume flow rate into the compressor.
The flowrate (q) per unit lenght (ft^2/s) over the spillway shown below is a fuction of the upstream heah H, the acceleration due to gravity g, and the spillway height P.
Obstruction due to underground electric lines requires that the x coordinate location of point C must be three feet as shown in the figure, as opposed to 1.5 ft for point B. Determine the magnitude of the resultant of the two forces
Two ropes are attached to the eye bracket. The resultant force R of the two forces equals 1000-lb and the line of action is directed along the x-axis. if the magnitude of force F1 is 250-lb, determine the magnitude of force F2 and the angle
During a 1.5-hr storm, 1.3 in. of rain fell during the first hour, and 0.4 in. of rain fell during the last half hour. The average flow in the downspouts was 1.7, 3.6, and 3.4 ft3/sec for each of the half-hour periods.
