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)?

It rains 3.0 in. on a 20.0 acre watershed. What is the volume of rainfall excess if 30% of the watershed area is a lake and infiltration on the soil is estimated at 1.0 in. What is the total volume of runoff.
Estimate the power needed to overcome the aerodynamic drag of a person who runs at a rate of 100 yds in 10 s in still air. repeat the calculations if the race is run into a 20-mph headwind: a 20-mph tail wind.
An aluminum link is subjected to axial tension. The loading is limited by the conditions of not yielding and not elongating excessively. The yield limit is satisfied if the stress remains below 50%of the 325M Payield stress.
