Document Summary

Do not separate pages from the answer book. Water (16 c), cp = 4. 18 j/g c; p = 1000 kg/rn3; t. Pv=nrt; r = 8. 314 kpa l/mol k; raoult"s law pi = yi ptotai = xi p(t) k = 1/(4te0) = 8. 99 x 109 nm2/c2; f, = 8. 85 1012 c2/nm2. = lf" ; f = 96485. 3 c/mol, hence, e = 1. 602 x 10"9 c q0 q. I = - ca (dv/dx); j = -da (dc/dx); q = -ka (dt/dx) Q (w) = k 23tl (at)/ln(r0/r); q = a (at)/(axi/ki+ ax2/k2 + ax3/k3) Q (w) = u a dtlm = u a (at2 - at1 )/ln(at2/at1 ) The city of montreal has announced plans to install heated sidewalks; construction will begin on. The initial installation is a 670 in length, which is 3 in wide. A network of tubes will be installed in the concrete (kconcrete = 0. 50 w/mk), and a depth of 2 cm.
