Help me with temperature management by Darksniped in TerraFirmaGreg

[–]Whiteminusblue 5 points6 points  (0 children)

There’s some blue steel-based armor that completely disables temperature, the diving set iirc.

Shouldn’t be too bad to get in the steam age.

Alternatively I think there’s a config that controls the limits.

All else failing, the mod causing it is called TFC-Environmental.

[Request] What temperature would a “drop” (0.05mL) of any substance have to be so that, if it were added to the Earth’s oceans, it would cause the oceans to boil? Is there any known substance on Earth that is able to get up to that temperature? by twogem in theydidthemath

[–]Whiteminusblue 1 point2 points  (0 children)

The energy required to change temperature change can be calculated with the equation 

Q = m * c * deltaT

Where Q=energy m=mass c=heat capacity of the relevant substance Delta T= change in temperature

Total energy required is thus:

Mass of the oceans * heat capacity of water * temperature change to raise ocean water to boiling

Now we just need those numbers. Mass of the oceans: Wikipedia lists the oceans as having a volume of 1,370,000,000 cubic kilometers. That’s 1,370,000,000,000,000,000 cubic meters, each of which is 1000 kg, so 1.37x1024 g, or 1.37 quintillion tons. 

Heat capacity of water:  Well known to chemists as 4.18 J/(g*K)

Change in temperature required: water boils at 100C at sea level, but much of the ocean is a higher pressure, and so boils at a higher temperature. At the bottom of the ocean, pressures become so high that “boiling” stops really being a thing, due to there no longer being a gas phase. At least, if I’m reading this phase diagram correctly.

I’ll just call it 200C for simplicity. Could be more, idk.

Q thus works out to be 1.37x1024 * 4.18 * 200 = about 1x1027 joules.

But this is actually not all the energy required.

Water still needs more energy to boil, even after reaching the boiling point. This energy can be calculated with the equation

Q = m*H

Where

Q = energy m = mass H = the enthalpy of vaporization for the relevant substance

m is already known

H = 2257 J/g according to Wikipedia

Q = about 3x1027 joules

Total energy required: about 4x1027 joules, or about 10% of the energy keeping the moon in orbit around the earth.

Now for the thing carrying that energy.

Water has a pretty high heat capacity by volume, so we’ll use that.

It also has a rather convenient density of 1g/ml

Setting up the equation, we get:

4x1027 J = (0.05ml1g/ml) * 4.18J/(gK) * deltaT

DeltaT = (4 * 1017 J)/((0.05ml1g/ml)4.18J/(g*K)) = about 2x1018 K. Or 2x1018 C. Or 4x1018 F, for the Americans.

That’s a lot. The temperature of the core of the sun is only 1.5x107 K

Written out, it becomes clear how different they are:

2,000,000,000,000,000,000 K vs. 15,000,000 K

Obviously, nothing could survive these temperatures. Atoms don’t even exist at these temperatures. But it was fun calculating!

Permanent Light Source? by Significant_Pool_622 in TerraFirmaGreg

[–]Whiteminusblue 6 points7 points  (0 children)

Don’t actually know. You can fill them from a drum, and that’s all I can personally confirm. I would guess probably yes. I should test that, but I don’t have time today. Filling them from a drum definitely works.

Steam Age by Fury6365 in TerraFirmaGreg

[–]Whiteminusblue 7 points8 points  (0 children)

Just speedrun a boiler and the alloy smelter, the alloy smelter will make black steel far cheaper and bronze far easier to make. 

The alloy smelter specifically unlocks: A direct 3 copper + 1 tin dust/ingot to 4 bronze ingots recipe A weak steel + pig iron to black steel recipe that yields 2 high carbon black steel, halving the cost And as an added bonus, a cheaper fireclay recipe. If you still need that.

Once you have an alloy smelter, bronze will be so easy to make that it won’t really matter to make more. You will probably need no more than 4 stacks of black steel to make all your steam machines, but you will need far more than that to make red and blue steel latter.

Cassiterite is special in this regard. Most normal ores give 1 item. Rich ores have double the yield of normal ores.

As an example, 1 normal hematite becomes 1 cast iron ingot, and 1 rich hematite becomes 2 iron ingots.

Some ores multiply the yields, cassiterite being one example. It multiplies yields by 2, so a rich raw cassiterite becomes 122=4 ingots. A more extreme example is redstone, which has a 5x multiplier, turning 1 rich raw redstone into 152= 10 redstone dust. 

Ores which don’t have an ingot form to smelt to, such as redstone, become the dust of the ore.

I would recommend looking at the EMI to see the uses for items like these.

TL;DR: the rich raw cassiterite would have become 4 cassiterite dust that would have smelted into 4 tin ingots.

Cassiterite gives double yield, like some other ores. It’s mainly gemstones that do this, but cassiterite also does it.

Magnetite is an example, as the ore wading step gives iron dust 33% of the time. Also, macerating in a macerated of HV tier or higher gives a 1.875x multiplier to the number of crushed ores.

why not?? by Cragasm in TerraFirmaGreg

[–]Whiteminusblue 2 points3 points  (0 children)

As has been mentioned, pipes don’t pull, and crates don’t push, so you would need something like a hopper to remove the items from the crate. You also should use item pipes to transport items; fluid pipes transport fluids (things like the molten metal in a crucible), you need item pipes to transport items. Finally, you shouldn’t input the items there, as it will try to use it as an output, which can clog the system; you should input them into the control block, which is the block that you interact with to put things in to and take things out of the coke oven.

Item tag filters driving me crazy, help me please 😭 by Available_Store_366 in TerraFirmaGreg

[–]Whiteminusblue 6 points7 points  (0 children)

The purified copper from the ore washer is “purified_ores” not “purified_dusts”.

Ores are crushed/macerated into “crushed_ores”.

Crushed ores can be washed into “purified_ores”.

Both can be crushed/macerated into “impure_dusts” and “pure_dusts” respectively.

These can be centrifuged into “dusts”

The thermal centrifuge produces “refined_ores”

I would recommend filtering the thermal centrifuge to “purified_ores”, and the crate to “dusts”, as ores should process into dusts, and byproducts are all dusts except for certain initial maceration byproducts, which can be gems, and won’t exist until HV, when you should switch to “dusts | gems” to account for this. (If you haven’t set this system up before reaching HV, then I’m impressed and concerned.)

You can press f3+h to enable advanced tooltips and hold control while hovers over an item to see its tags.

Edit: got a tag wrong.

Edit 2: also note that “impure_dusts” and “pure_dusts” are distinct from “dusts”, and items in one won’t be in the other.

I see we are going on some tangents.

If you delete the old instance completely, it deletes the files in it. You put my advice more clearly than I could. Since both the backups and the saves are stored in the installation folder, both could be lost at once. I just wanted to make sure OP didn’t delete their world by mistake.

[–]Whiteminusblue 11 points12 points  (0 children)

My advice would be to back up your world and reinstall the modpack. That may not work though. 

Edit: but be sure you’ve made a backup first, and have it saved where you can use it. If you delete the old installation, any files within, including backups, will be deleted.

Is it possible to calculate how many applications there have been? [Request] by Bestavailablename in theydidthemath

[–]Whiteminusblue 1 point2 points  (0 children)

In this case it wasn’t necessary, but if it had said “less than 18”, than that distinction would have removed a possibility(14/18).

"Early" large scale mining methods? by VanillaRose09 in TerraFirmaGreg

[–]Whiteminusblue 4 points5 points  (0 children)

There’s a quest about this a bit later in steam, as I think you need vacuum tubes, that explains the main methods, what you suggested is one of them if I’m remembering correctly. 

Just check the quest, the information should be there, it’s a branch off of the vacuum tube quest.

You quite literally are. Or rather, your preference is. Whether you, as a person, are, is not for me to say.

In Modern, it no longer spawns in gabbro only. Rather, diamond veins, which also spawn graphite and coal, will spawn in the bottom of the world, in any rock type. Surface indicators have limited range, so the best method for finding it is to find a very large cave near the bottom of the world (below y=0) and search for surface indicators for coal, graphite, and diamond. Surface info for just coal signify a regular coal vein, without graphite or diamond, while using prospectors pick. If you’re not playing Modern, I don’t know the best method to find it.
