Answer:
- <u>Translated from Portuguese language:</u>
"The gaseous coal is then burned in a gas turbine cycle and part of the residual heat from the exhaust gases is recovered to generate steam for the steam turbine. Currently, the construction of such plants costs about $ 1500 per kW, but their efficiency is about 45%. The average calorific value of coal is about 28,000,000 k J per ton (that is, 28,000,000 k J of heat released when 1 ton of coal is burned). If the mill is to recover its cost difference in five years from fuel savings, determine what the price of coal should be in $ per ton?"
Explanation:
- The price of coal will be around 37 $ per ton. As, a source of energy the coal is more involved in the different industrial and mechanical processes and increases the level of efficiency of different machines by providing a more unique way to obtain greater results.
Creo que la moraleja de la historia no es demasiado agradable. La razón por la que creo que la historia se basa en ese aspecto es que el camello al final de la historia actúa de manera egoísta. El camello solo se preocupa por si mismo. Al camello no le importa lo que el maestro siente. El camello aprovecha la simpática personalidad del maestro.

I think the moral of the story is not too nice. The reason why I think the story is based on that aspect is that the camel at the end of the story acts selfishly. The camel only cares for itself. The camel does not care what the teacher feels. The camel takes advantage of the sympathetic personality of the master.*
