I have set up three combustion engines to a quarry, all three of them are cooled by one pipe coming from two pumps.
P - Pump Q - Quarry E - Engine P+ +--E +-+-EQ P+ +--E
Sometimes the engines overheat. Should I set up one pump for each engine? This sounds like a bit overhead to me.
Additional question: Where can I find detailed information on how to power machines optimally (eg how many engines do I need to optimally power machine xyz), cooling engines etc.
