PLease check my formula

[beowulf2010]

I'm having one of those days and I'm not quite trusting my formula for minimum Wheezewort to keep a geyser under 95C to not stifle the WW.

First, the geyser output is easy...

Geyser output: Displayed output * (Active Eruption Period / Total Eruption Period) * (Active Period / Total Active Period)

Then, the effective cooling of Wheezewort in Hydrogen:

1,000 g/s * 2.4 g/s/c * 1C = 12,000 DTU or 12 kDTU

The part I'm not trusting myself on is taking into account the Specific Heat of the geyser...

(Geyser output (in g/s) * Specific Heat of geyser output (g/s/C) * (Output Temperature - 95)) / 12,000 DTU

So for the following Cool Steam Vent: 7.6kg/s, 177s every 520s, and 41.6C every 83.3C

( (7,600 * (177/520) * (41.6/83.3)) * (110C-95C) * 4.179 ) / 12,000

Resulting in 9.93 Wheezewort needed to cool all output down to 95C or under to keep the Wheezeworts from stifling.

This doesn't feel right, so, what did I do wrong? (Other than choosing to passively cool geyser outputs with Wheezeworts instead of liquid cooling them with other stuff.  )

You came to the same result as me when I was trying to cool a cool steam vent. I think your formula is quite good in fact. Wheezeworts do not cool a lot in reality.

You could maybe let some of that heat go through a biome. I would not heat a biome that much even in 500 cycles if you put down like 6 wheezeworts instead of 10 ^^

Seems about right to me.  Keep in mind that that's the average amount of cooling power you need though - you'll need more to condense steam fast enough to not over pressurize.  That's why I always use central cooling and distribute it.

I consistently observe around 90C with one ATEN cooling a cold steam vent. An ATEN is around 8WW, so you are not far off. To keep the WWs from stifling, just put a hydrogen loop through the WWs and the water that does not fully heat up that hydrogen, i.e. at the end of its pass though the water it is still 10C or so colder than the water. Cooling effect will be the same, but the WWs will be much colder to compensate the higher thermal resistance.

I found that having >= 2 tiles of water already somewhat colder below the vent and diamond heat-shift plates from there to the 2nd tile of the cold steam geyser works very well and reliably prevents over pressure. Other materials do not work reliably, tried that in the last few days.
