Plateau Creek carries 5.0 m^3/s of water with a selenium (SE) concentration of 0.0015 mg/L. a farmer starts withdrawing 1.0 m^3/ of the creek water to irrigate the land. During irrigation, the water picks up selenium from the salts of the soil. One-half of the irrigation water is lost to the ground and plants, and the other half is returned to Plateau Creek. The irrigation run-off to the creek contain 1.00 mg/L of selenium. Selenium is a conservative, nonreactive substance, and the stream does not pick up more selenium from any other source.
a) If the farmer irrigates continuously, what will be the steady-state concentration of selenium in the stream downstream from the farm (after the irrigation run-off returns to the stream)?
When measuring a distance AB, the first taping pin was placed 1.5ft to the right of line AB and the second pin was set 1.5 ft left of line AB. The recorded distance was 236.89 ft. ( Assume 3 taped segments, the first two 100 ft each.)
The 12 in diameter cast iron pipe is 2000ft long, the water surface is El 200 in the reservoir on the left B. El 175 on the right. A. Find V and Q by hazen-williams for a new cast iron pipe (Chw=130) Neglect entrance, exit and local losses.
The James Rives flows in from the East at 320 m^3/min and joins the Jackson River flowing at 605 m^3/min just outside the town of Charlotte, NC. The concentration of BOD in the James River is 14 mg/L
A water pipeline system is made up of three links in parallel. In any given year, on average, 99 in 100 pumps do not fail. The conditions in the links are statistically independent of each other.
A notched beam, machined from AISI 1020 steel is subjected to reversed bending. Determine the endurance limit Se. Assume the survival rate of 99.9 percent and Cs = 0.75 and that the fatigue stress concentration factor is Kf =2.5.
Two kilograms of steam at 300kPa and a quality of 75% are heated in a closed container until a pressure of 600kPA is reached. Determine the final temperature of the steam and the heat input.
The grade elevation at station 25+00 is to be 946.52 ft. What will be the grade elevation at station 34+86.20 if the grade linerises at the rate of 1.785% between these two points?
A 2500-lb car (CD = 0.35, Af = 25 ft^2, and ? = 0.002378 slugs/ft^3) has 14-inch-radius wheels, a drivetrain efficiency of 90%, an overall gear reduction ratio of 3.2 to 1
To apply shock loading to an artillery shell, a 20-kg pendulum A is released from a known hight and strikes impactor B at a known velocity Vo. inpactor B then strikes the 1-kg artillery shell C.
The "sea-level adjusted" pressure at the airport was about 30.57 inches of mercury. Assuming the density of air is 1.30 kg/m3 and the gas constant for air is 287. J/(kg K), calculate the temperature of the air in Fahrenheit.
Derive the expressions for the concentration exiting a CSTR and a PFR for a zero order removal reaction. Which reactor design is more efficient in terms of volume and hydraulic retention times
a simple beam with a pin support at A on the left side of my beam, and a roller connection 20 feet away on the far right side of the beam labeled C, with the midspan point (10 feet) labeled B.
