Debug mode (Editor).
input: 1000 g of crude oil (SHC.1.69 (J/g)/K ) at 348.5 C, 1000 g/sec through abys. pipes
pipe in a middle : one pipe (igneous rock (SHC 0.2), 100kg ,20C , one tile inside vacuum)
output: crude oil at 329.6 C , pipe (igneous rock), 28C correct ? wrong!
Math: resulting oil lost 18.9 degrees C, what is equal 1.69*1000g*18.9C = 31.9 kW, igneous rock pipe gained 8 degrees C ,100000g*8C*0.2 = 160 kW,
so question is: why did it heat so much (5 times more than needed)
Steps to Reproduce
open save file and let oil flows through pipes , or build equal set up in editor
