18:10 -- RE: Relationship between RPS, Load, and Heat ; Full disclosure, I'm a new player and mostly I've been using the Workshop to investigate player-built ships, so I'm hardly an expert. However, I had my first eureka moment in a medium sized oil tanker that featured a 5-gear manual transmission on its main engine. That finally made most of the numbers make some sense to me.
Definitely going to have to try some stuff here. I recently built a setup for my large ship using 8 5x5 modular engines and have been trying for weeks to get it to cool right. Its good around sawyer and anything north, but will not stay cool enough in the hotter region. Thanks for the video ! Hopefully i can get it sorted
Hey Cap. Really helpful vid, as I'm working on my first modular engine at the moment. Regarding you saying the electric motor setup is better for running the impeller than using the RPS connection, due to the increased load on the engine: If you're using an alternator on the engine to provide the electricity for that motor, wouldnt your load end up being greater than the direct RPS power? Because of the inefficiency of converting power into electricity and back again to power?
It isn't. The motor is only running at .185 so the electricity used is very low. You can see in the video it runs at a higher RPS and load is lower. The electricity used is negligible
Love the cooling tutorial, but there's a bit of misinformation. The examples in the video make it seem like the electric motor is free power. The impeller w/ electric motor is still stealing engine power, it's just using the load you've put on the as the control load, or if infinite power is on it's just free power. Would be interesting to see the results the same static load, but one engine using direct engine RPS, and another using 1+ alternators/generators solely used to power the electric engine. Overall it's a great cooling experiment. I've been using the rps to impeller setup since you talked about it in a live stream a few weeks back. Didn't know the flow rate caps out regardless of engine rps. Going to tweak my builds accordingly now, no point in stealing additional rps for no reason.
I talk about it at 3:48. The electric motor is set at .185 The amount of electricity used is negligible. I don't know how that's misinformation as I clearly address it.
@@CaptainCockerelsI think inneedofmedication is right, the test is slightly flawed. You are looking only at the output of the generator you use as test load, but in all other examples but the electric motor one, 100% of that output value is usable power for stuff outside the engine (e.g. moving a car), in the example with the electric motor some % of that is being used by the cooling system, and this cost is not visible in this test. This is not negligible either - an alternator at @20 rps cannot keep up with the electric motor at .185 throttle, meaning you HAVE to have a generator on the output side to steal some of that power. If I were to guess, feeding the impeller straight from rps is probably still more efficient, as it avoids transforming energy from kinetic to electric back to kinetic.
Thanks for the vid! So at 11 mins or so you were having issues with the flow rate on your small pumps. I seem to remember that there has been a long-standing bug in this game where the order in which you place your pumps down can affect the flow-rate calculation. Usually I just pick them up and place them down again and that fixes the fluctuation. Its a really flaky bug so I have no idea if that will work in this case.
wow, great vid

Great video! This will help me.
I'm really looking forward to the next video. Cooling my engines is always a struggle for me.
Amazing video cap

this is a lot of good information to know but... what about the modular engine pumps? do they act as imperllers or are they morel/ess efficient?
It's a series, there will be more videos.

Could be it, thanks
