not that write it in paper please provide clear answer with the drowing same grophesConsider the two mixing tanks in series shown in Figure The tanks have constant volumes
and constant volumetric flowrates The feed stream may
contain a dye of concentration that can be adjusted by an upstream unit. Derive a math
ematical model for the dynamics of the dye concentrations and in the two tanks, and
calculate their responses for the following cases.
The feed is pure water, but there is leftover dye in the first tank from a
previous experiment, with initial concentration of The second tank
initially contains pure water
The feed is initially pure water, the tanks initially contain pure water, but at time the
feed is suddenly switched to a solution of dye of concentration
The feed is initially pure water, the tanks initially contain pure water, but at time the
feed is suddenly switched to a solution of dye of concentration up to time
min, when it is switched back to pure water.
The same amount of dye as in the previous question is delivered during an infinitesimally
small time period
The feed is initially pure water, the tanks initially contain pure water, but starting at time
the feed contains dye with linearly increasing concentration at a rate of
