2. A jacketed vessel is used to cool a
process stream as shown in Fig. E2.The
(i) The volume of liquid in the tank V and
the volume of coolant in the jacket
remain constant. Volumetric flow rate
qF İs constant but q, vanes with time.
(ii) Heat losses from the jacketed vessel
(ii) Both the tank contents and the
jacketed contents are well mixed and
have significant thermal capacitances
(iv) The thermal
I capacitances of the tank
wall and the jacket wall are
negligible
(V) The overall heat transfer coefficient
for transfer between the tank liquid
and the coolant varies with coolant
flow rate
where U[Btu/h fF
K-constant
Derive a dynamie model for this system.
(State any additional assumptions that you
make)
