GIVEN: A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the pollution to disperse horizontally or vertically except in the direction of the prevailing winds (for example, a town located in a valley with an inversion layer above it). Consider a town having an inversion at 250 m, a 20-km horizontal distance perpendicular to the wind, a windspeed of 2 m/s, and a carbon monoxide (CO) emission rate of 60 kg/s (see Figure P1.16 on pg. 43 of the text). Assume the CO is conservative and completely mixed in the box.
FIND: What would be the CO concentration in the box?
A before-and after speed study was conducted to determine the effectiveness of a series of rumble strips installed approaching a toll plaza to reduce approach speeds to 40 mi/h.
The wastewater treatment plant for Pine City discharges 1 × 105 m3/day of treated waste to the Pine River. Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day.

Compute the water table profile drawn in part B. Provide a detailed description of your methodology, and limit your solution to include only 4 image wells. Plot the profile, and provide drawdown amounts at X = -400 m, -200 m, -100 m, 100 m, 200 m,..
What is work? Why is it path dependant? Derive the expression for reversible work from a closed system containing a simple compressible substance.
Water flows past a triangular flat plate oriented parallel to the free stream as shown. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
Write a balanced net equation for the reaction of the hydrogen ascorbate anion with water where hydrogen ascorbate acts as an acid.
Peg P is driven by the fork link OA along the curved path described by r = (2*theta) ft. At the instant theta = pi / 4, the angular velocity and angular acceleration of the link are (theta-1dot) = 3.0 rad/sec and (theta-2dot) = 1.1 rad/sec^2
