The mixing tank has inflow and outflow tubes and a stirrer that keeps the concentration uniform at all points in the tank. The tank is initially filled by a volume V of solution, formed by dissolving a given solute in a solvent, with concentration Co (measured in kg/l); The inflow tube carries a solution of different concentration Cin than the initial concentration; the volumetric flowrate is Qin The outflow flowrate is Qout and, due to the well-mixed assumption, the outflow concentration has the same concentration as the instantaneous concentration of the tank. (i) Derive the differential equation governing the instantaneous concentration in the tank; (ii) Assume the tank volume is 1000 l, the volume initially contains 10 kg of salt, the rate of inflow is 2 l/s, the inflow concentration is 0.005 kg/l and that Qin = Qout (in other words, the out ow pipe carries away the over ow).
Required:
a. Calculate and plot the instantaneous concentration of salt C(t);
b. Calculate the time required to produce a solution of concentration 0.008 kg/l.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
