According to the documentation, how much did stephen tvedten owe in fines by april 5, 1998? even if he were to belatedly comply with the order by the april date, did deq given him any way to avoid this bill? deq would not respond to mr. tvedten’s phone call, so did his letter of december 19, 1997 have any other purpose than to annoy david price? ( read the april 5, 1998 item from the detroit news carefully before responding.) how could "debris" on the shore of a stream (not a river) cause additional damage in december in michigan? if the dams are not rebuilt (the neighbors killed both beaver families), and thus are not holding back the stream, what would cause additional flooding on the lower landowner’s property?

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
