Help with calculating efficiencies?Watch
I have tried doing each process so for example chemical to energy the way I see it is it is 95% efficient with 5% wasted. But I don't understand what the extra values are for like electrical to thermal because it doesn't state anything about it in the question. Help!!!
chem -> thermal 95%
thermal -> mech 40%
mech -> electric 95%
which tbh should come out somewhere in the right area for the efficiency of a real world coal burner (i.e. between 30-40%)
but it's a confusing diagram, (sankey diagrams are preferable)... I think it's trying to show that all energy inputs to the station ends up as waste heat eventually - and I'm not sure what the 7% thermal to electrical is from either.
