A well-stirred tank of volume V= 5m^3 is filled with brine,
inwhich the initial concentration of NaCl at t=0 is Co=1
kg/m^3.subsequently, a flow rate of Q= 0.01 m^3/S of pure water is
fedsteadily to the tank, and the same flow rate of brine leaves
thetank through a drain. Additionally, there is an ample supply
ofNaCl crystals in the bottom of the tank, which dissolve at
auniform rate of m=0.05 kg/s. why is it reasonable to suppose that
the volume of brine in thetank remains constant? Derive an
expression for the subsequentconcentration C of NaCl in terms of
Co, m,t,Q and V. make a sketchof C versuse t and label the main
features. Assuming aninxhaustible supply of crystals, what will the
concentration C ofNaCl in the tank be at t=0, 10, 100, and infinity
S? carefully define the system on which you perform a transientmass
balance?
