Find the period of the alternating vortices shed from a boulder in a river under the following conditions: diameter of cylindrically-shaped boulder is 1 m; approach velocity is 1 m/s; water temperature is 15.6 C. Assume the water approaches the boulder as if the boulder were a cylinder standing on its end.
compose a list here of the geological terms that you encounter in this reading that you could not define and explain in a test situation.
a layer of clay, 5m thick, overlies a deposite of sand, 5m thick, which is underlaid by rock. the water table in the sand is sub-artesian with a level at 2m below fround level. the saturated unit weights of the clay and sand are 21 and 16 KN/m^3 r..
If the coefficient of static friction between the cord and the fixed peg at B is fs =0.25, determine the minimum weight of the bucket that will prevent the block from sliding down the incline.
A reservoir with a length of 20 km and width of 3 km has a flood inflow of 1000 m^3/s. (a) If exit flow is restricted to 500 m^3/s, how fast is the water level rising in the reservoir per day
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. Determine the velocity (V)
A reservoir discharge into a 60-inch concrete pipe (rough surface) that discharges freely. what is the pressure in the pipe at point A consider friction, but neglect minor losses.
Determine the force at the circular endcap and its location relative to the bottom of the pipe. If there is a hinge at the bottom, what external force would need to be applied to the top to prevent rotation
Presedimentation can reduce the suspended solids concentration of raw river water from 500 mg/L to 200 mg/L. How many pounds of dry solids does this represent per million gallons?
Estimate the buoyant force on 10'x10' by 2' deep balsa (SG=0.2) raft with you in it. How deep is it in the water. Be sure to draw well leveled schematic of the system.
Water flows steadily through a horizontal 30 degree upward bend. The inlet diameter is 0.3 m, the velocity is 12 m/s, and the pressure is 128 kpa gage. The outlet diameter is 0.38 m and the pressure is 145 kpa gage.
You wish to retire at age 66 and at the end of each month thereafter for 30 years, to receive $5000. Assume that you begin making monthly payments into an account at age 24.
Calculate the area of a piece of property bounded by a traverse and circular arc with the following coordinates at angle points: A (1275.11, 1356.11), B (1000.27,1365.70),C (1000.00, 1000.00),D (1450.00, 1000.00)
