Found it. It's right at the top of the big triangle and above the circly bitNOPE !!!
Pics isa must if yer fitting shinny bits.
Oh dear, hadn't gone rusty had it??New subframe in yesterday…

But Boyles law considers constant tempThat IS it but it assumes constant temperature.
If you heat a gas in a constant volume, the pressure of the gas inside it will rise in direct proportion to the temparature.
Which is why a piston in a car engine flies down (i.e. volume increases) when the mixture explodes. The volume increases as the temperature and therefore the pressure increases.
I believe the equation with all three in it is
P1V1/T1 = P2V2/T2
Yes and maybe that's the trick of the brain. It says Triangle and colours it Orange then colours a little bit that is in no way connected to the question.but its got three angles, must be a triangle? If not, the only triangle in the puzzle is the big one. And that's an easy sum to do - 1/2 base x height.
Me neeva!NOPE !!!
Front 1 next then?You’d have to look at the bits of the forum where the proper landies wot don’t leak and rust are…

I don't understand your comment, the first thing I said in the post was "That IS it (i.e. Boyle's Law) but it assumes constant temperature." So I was agreeing wiv you!But Boyles law considers constant temp
Check out your back up, Wiki or any other and you will see temp is always mentioned as "constant".

I then just went on to explain how the full gas PVT equations work and allow you to consider what happens when temperature changes. I agree the name of the equation, P1V1/T1 = P2V2/T2 isn't Boyle's law but nor is it it Charles' s law neeva. In fact I couldn't find a name for it beyond "Gas equations"
It does - a very strange play on the lighting.Car in the background looks like its been shunted
"which is unpropelled" ...well at least until youz guyz start propelling it!!!Nice day today, flat calm too. Just as well we are moving a 80ft barge which is unpropelled.
Should be fun.
Do you not have one of those expansion chamber type things? We do, and ours is heated by solar, as I think you will remember.Then don't add a "T" in Boyles law.
Its thermal expansion, but is difficult to narrow down as the volumes changes , so pressure changes.
He should have just followed simple instruction's and pricked it .
We have mains supplied hot water tanks, they heat water but don't explode because they have calculated the length of the outlet to leave an air space to allow for expansion due to heat, they don't expand. Oh and they are stronger than a plastic bag .

Like the white thing in this pic.

We do also have mains that can heat it when there isn't enough sun.
Is it a goal to be largely "off-grid" and independent?Nope.
We have an expansion "ball" on the solar (closed system). But the hot water tank outlet comes from the top, but not at the top so allows for expansion of the water due to heat. Just like the "ball" I.E has an air space closed system.
But your pic shows a closed system tank so that 250L(?) tank needs expansion into the "ball"
Our 500L buffer tank (heated by solar but separate water) is ATM (open vented to tank)

Sort of, Not entirely off grid but hate to waste the sunshine available.Is it a goal to be largely "off-grid" and independent?
