How to build dynamic simulation.
Interaction between set points and process variables
It is an extension of steady-state whereby time-dependence
is built into the models i.e. accumulation of mass and energy.
Control of real processes are possible.
The calculations are more complex and time consuming.

Heat Exchanger Hot water at 500°C and 2000psig is
used to heat cold stream of water in a shell and
tube heat exchanger. The inlet temperature and
pressure of the cold stream is 50°C and 260psig,
respectively. The outlet temperature of the cold and hot
streams are 300°c and 360°C, if the flow rate of the
hot stream is 100kg/h,determine the flow rate of the
cold stream passing throughout the exchanger.
Design of Heat Exchanger V10 An example:
Design an exchanger to sub-cool condensate from a methanol
condenser from 95°C to 40°C. Flow-rate of methanol 100,000 kg/h.
Cooling water will be used as the coolant, with a temperature rise
from 25°C 40°C.
