An energy efficiency project has a first cost of $300,000, A life of 10 years, and no salvage value. Assume that the interest rate is 9%. The most likely value for annual savings is $60,000. The optimistic value for annual savings is $80,000 with a probability of 0.2. The pessimistic value is $40,000 with a probability of 0.3.
a) What is the expected annual savings?
b) The expected PW?
Suppose a sample of the 90 °C air is put in a closed variable-volume chamber containing a mirror, and the pressure is raised at constant temperature until a mist forms on the mirror. At what pressure would the mist form
