hmm. FTB wiki says that 1 HU will raise the temperature of 100 kg of mass by 1 K. So heating 875kg of iron to Δt=1760K (env temp counted) requires… exactly 15 400 HU. (Or ~6 secs using chromium bb. Checked it in a lab right now. It’s correct.)
Are you sure that 1000KU is needed? Basic chromite engine can produce that amount in 10 ticks. Not 10 000? As I wrote before, my setup includes an 80ku/t steam engine, which is able to produce around 10 000 ku in 6 seconds. [Or maybe I just lose a zero somewhere {but I don’t think so}]
So,
15 400HU / 10 000KU = 1.54HU per 1KU
or
15 400HU / 1000KU = 15,4HU per 1KU
Which means I calculated it kind of right. My 2/3 ku/t per hu/t is 1.5 hu/t per ku/t. (If I calculated it right now)
Thanks for replying again. I remembered the good old times, in school, then I loved physics exercises.
(But solved ‘em almost every time wrong)
P.S Unit of steel is an Ingot as I count or nugget or 0.1pt? Hell there is around 10 times difference. Good night anyway.
