When the capacity of a hydrogen plant is doubled, the capitalcost increases by 73%.
1.1. Why does the capital cost not double when the capacity isdoubled? (2)
1.2. Derive an equation that relates the capacity to the capitalcost for this particular hydrogen
plant. (6)
1.3. If the six-tenth rule is used, what would be the increase inthe capital cost if the hydrogen
plant capacity is doubled? Compare this increase with the 73%mentioned above and
comment. (5)
