Snnta Ana winds nre hrgh-velocity winds that originate in the Mojave Desert just to the northeast of Lw Angeles. Load the Smog in Los Angeles Raslin Web Module. Use the data in the mod- ule to work part 1-14 (a) through (h) given in the module. Load the living example polymath code and explore the problem. Fur part (I), vary the parameters D,,, n, and b. and write a paragraph describing what you find. There is heavier traffic in the L.A. basin in the mornings and in the eve- nings as workers go to and from work in downtown L.A. ConscquentIy, the flow of CO into the L.A. basin might be better represented by the sine func- tion over a 24-hour period. PI-ISB The reaction is to be carried

C4 = O.OICA,) when the entering molar flow rate is 5 molfh, assuming the reac- tion rate -rA is: mol (a) -r, = k with k = 0.05 - (Am.: V = 99 dm3) h . dm' (b) -rA = LC, with k = 0.0001 s-I dm' (c) -rA = kc: with k = 3 - (Ans.: r/csre = 66,000 dm") moE . h The entering volumetric flow rate is TO ddlh.
