Welcome
This is a template to create an Instructional
Design Document of the concept you have selected
for creating animation. This will take you
through a 5 section process to provide the
necessary details to the animator before starting
the animation. The legend on the left will
indicate the current status of the document. The
Black coloured number will denote the current
section, the Turquoise color would denote the
completed sections, and the Sky blue color would
denote the remaining sections. The slides having
'Instructions' would have a Yellow box, as shown
on the top of this slide.

Definitions and Keywords
1

• Mass transfer- Transfer of mass from high
  concentration to low concentration.
• Mass transfer coefficient (kL)-The mass transfer
  coefficient is a diffusion rate constant that
  relates the mass transfer rate, mass transfer
  area, and concentration gradient as driving
  force.
• Phase- A physically distinctive form of a
  substance, such as the solid, liquid, and gaseous
  states of ordinary matter
• kLa-The product of the mass transfer coefficient
  for transfer from one phase to another (kL) and
  the interfacial area (a) between the two phases.
• Sparge-To introduce air or gas into a liquid.

• Two buttons should appear

The experiment tab will give an animation of the
actual experimental procedure, while the
mechanism tab will involve an explanation of the
actual mechanism of mass transfer in the in
indicated two phase system.

Refer To Diagram on the next slide

• The interface will show a reactor, filled with a
  liquid, as indicated in the diagram
• Initially the gas bubbles will not be visible.
• The pump source will be filled with solution.

1, 2) This is the bioreactor in which the mass
transfer characteristics will be studied. The
graph will give a plot of the dissolved oxygen
verses time. 3)The reactor has a sparger for
bubbling oxygen from the bottom, an agitator for
mixing, and facility for adding the oxygen
consumer through the hopper. 4)We begin to
sparge the reactor with oxygen. 5)We begin to add
the sodium sulphite. When the rates of oxygen
addition and consumption are equal, the
concentration of oxygen becomes constant as
indicated on the graph. 6)The oxygen addition is
stopped. The concentration of dissolved oxygen
begins to fall. 7) We begin to bubble the oxygen
again, and the dissolved oxygen begins to rise,
as can be seen in the graph. The dissolved oxygen
finally reaches a saturation value.
(contd from previous slide.)? Then, the oxygen
bubbles will stop rising. The graph will indicate
its straight line down. This will happen for
another 5 sec. Then the oxygen bubbles will start
to reappear, and the graph will begin its last
curved portion. This will happen for 10 sec. The
graph will finally be a horizontal straight line
again.

Questionnaire to test the user

• A small, (5 questions) questionnaire can be
  created in the next slide, to test the user's
  comprehension.
• This can be an objective type questionnaire.
• It can also be an exercise, based on the concept
  taught in this animation.
