You are in charge to investigate the characteristic of a small river that can be assumed as a uniform and rectangular cross-section for modeling purpose. The width of the river is 10 ft, the depth is 1 ft, longitudinal slope of 0.001, and the Manning's coefficients is 0.03. To estimate travel times and dispersion coefficients, you injected 50 gm of rhodamine dye at one bank of the river because it will spread out soon enough. You also began the steady bubbling of propane, a gaseous tracer into the river at this location.
a. Your assistant is measuring the rhodamine concentration 1 km downstream. The data when converted to a spatial distribution at t = 2500 sec after dye release, show the following: 95% of the mass lies between 800 m and 1200 m at time t = 2500 sec. Estimate the longitudinal dispersion.
b. Your other assistant is measuring the propane (C3H8) concentrations, which are 75 microM at 200 m downstream and 52 microM at 1500 m downstream. What is the reaeration coefficient if it is assumed that no dilution occurred due to lateral flow?
c. How far downstream must your assistant go to collect the sample near shore that is representative of the entire channel cross-section?
The two disks each have a mass of 18 kg and are attached at their centers by an elastic cord that has a stiffness of k= 1.6 kN/m. Determine the stretch of the cord when the system is in equilibrium and the angle of the cord.
A $125,000 tractor trailer is being depreciated by the Stright Line method over five years to a final Book Value of zero. Half year convention does not apply to this asset, After three years the rig is sold for A
Iron and vanadium both have the BCC crystal structure, and V forms a substitutional solid structure in Fe for concentrations up to approximately 20 wt% V at room temperature.
Consider a 75-ft wide overflow spillway with no piers and a design head of 18 ft. The crest elevation of the spillway is 2400 ft and the streambed elevation just upstream of the spillway is 2350 ft.
The bottom of piezometers A and B are on the same flow line and 1000 m apart. The bottom of piezometer A is at 130 m and its water level is 160 m. The bottom of piezometer B is at 100 m and the water level is 150 m.
Data from service records show that the time to repair a certain machine is normally distrubuted with a mean of 65 min and a standard deviation of 5 min. Estimate how often it will take more than 75 min to repair a machine.
A conical tube of length 8 m fixed vertically with its smaller end upwards. The velocity head and pressure head at upper ends are 1.27 m and 2.50 m respectively. The velocity head and pressure head at lower ends are 0.203 m and 5.407 m respectivel..
a hollow steel shaft with an outside diameter of 400 mm and inside diameter of 300mm is subjected to the torque of 300 Kn. The modulus of rigidity for the steel is 80 GPa.
A soil has a total density of 1.80 Mg/m3. When fully dry, the soil has a density of 1.59 Mg/m3. The specific gravity of the solids is 2.57. Find the following soil parameters: a) Dry unit weight of the sample
A projectile is fired with an initial velocity of 800 ft/s at a target B located 2000 feet above the gun A and at a horizontal distance of 12,000 feet. Neglecting air resistance, determine the value of the angle at which the projectile is fired.
