The midterm will be on 12 October 2012 and will cover all material in the course, up to and including Ultrafiltration (membranes section).


# Understand various definitions of “interest” and how each is calculated and used: simple, compound, nominal, and effective
 
# Know how to calculate cash flows and exchange them for equivalent values at different times.
The midterm will start at 19:00, but be at the venue at 18:45. Please double check your location: the seating is exact, and you will be asked to go to the correct location.
# How do taxes affect the above?
 
# What if all cash flows are negative? (e.g., a public works project)
 
# Calculate values at any time period from the cash flow data  if the interest rate is different for different periods.
'''Answering questions in the midterm'''
# Be able to work forwards, i.e. escalate values to a future time point, or backwards, i.e. deflate all values to their present value
 
# Compare various methods of profitability mentioned in class
* You may bring in any printed materials to the midterm; any textbooks, any papers, ''etc''.
#* What are the advantages and disadvantages of each method
* You may use any calculator during the midterm.
#* What similarities do the measurements have? 
* You may answer the questions in any order in the answer booklet.
#* At what point in the planning of a project would each measure be appropriate?
* ''Time saving tip'': please use bullet points to answer, where appropriate, and '''never repeat the question''' back in your answer.
#* What are the measurements trying to represent?
* If anything seems unclear, or information appears to be incomplete, please make a ''reasonable'' assumption and continue with the question.
#* What are some simple measures of profitability that one could quickly do to see if a project makes any sense?

 
# The calculation of DCFRR requires a trial and error solution.  What is the most efficient way to accomplish this?
'''How to prepare for the midterm'''
# What are typical critical values for Payback Time (PT), Return on Investment (ROI), Discounted Cash Flow (DCF), and Minimal Acceptable Rate of Return (MARR)?
 
# Find one more common measure of profitability (Ex. Equivalent Annual Worth or Annuity). How is it calculated and how does it compare to other measurements?
* Understand the concepts being learned. My courses are not about applying the correct equation and solving.
# Discuss how the “value of money” is determined.
* As you've seen, there are only 5 to 6 equations we have learned in the past 5 weeks. Understanding how to use these equations, and how to interpret them, is important.
# What factors affect cash flow?  How are these factors calculated? e.g. inflation, depreciation, taxes
* Check that your answers are reasonable (can you really have a flow rate of 1050 \(\text{m}^3.\text{s}^{-1}\) through a pipe?)
# Set up a cash flow problem and calculate measures of profitability.
* Read the questions carefully: they are usually worded precisely. The biggest point where students loose marks is to answer only part of the question.
* Questions that you did on computer in the assignments: make sure you can repeat them by hand. Obviously not where you have to draw an entire plot, but make sure the calculations to draw that plot can be done for at least one or two points on the curve.
* ''Hint'': the last question covered in class today, 11 October, is important. Please don't worry about the concept of the limiting flux that was explained in the middle of the class.
