1.011  Project Evaluation

QUESTION: 

Part 2b asks to evaluate operation cost if traffic varies from 10000 to
100000 tons/year.  This is a problem, in that, according to my
calculations for operating an average of 9 hours a day, 25 days a month,
9 months a year, with the given constraints on lock time and speed, 
only the 75 ton boats can get more than 10000 tons of cargo through the
canal per year....

is the perscribed capacity a mistake, or have I messed up a calculation
somewhere?

ANSWER  (R.C.D.M):

100,000 tons per year would be 4,000 25-ton boats per year or 450 per month
for 9 months or 15/day or fewer than 2 per hour - and capacity is surely
much more than that.  So, I suspect that you have messed up a calculation!
