1.For the following conditions determine whether a CMFR or a PFR is more efficient in removing a reactive compound from the waste stream under steady state conditions with a first order reaction: reactor volume = 280m3, flow rate = 14m3/d, and reaction rate coefficient = 0.05 1/d.

2.Let a one-dimensional velocity field be u = u(x, t), with v = 0 and w = 0. The density varies a ?-?0(2-cos(wt)) Find an expression for u(x, t) if u(0, t) = U.
