Suppose you have a typical coal mining process composed of the following steps:
(1) Excavation -> (2) Crushing -> (3) Storage -> (4) Rail -> (5) Power Station
The idea is the coal is excavated out of the ground, crushed and processed, stored, and finally transported by a diesel train to the power station. It is very simplistic and probably missing some steps, but it's just for ease of calculation purposes.
Now I'm interesting in finding the energy loss in each component of this process, scaled down to 1KW.
For example, if I start of with 1KW at the beginning of the process (step 1), how much usable power would be available for me at the end (step 5)?
