How much H2O to add to make 1:1 Sugar syrup

Recommended Posts

How much water do I need to add per 100 litres of 2:1 (68 brix) to turn it into 1:1 (48 brix).

 

My maths brain is eluding me.

When I used to mix a single 25kg bag of sugar at a time I found that a 2:1 solution gave me around 30L of sugar syrup (i.e. 25kg sugar mixed with 12.5L water). So to make that into a 1:1 solution I'd have to add another 12.5L of water to the 30L of sugar syrup.

So to convert 100L of 2:1 sugar syrup to a 1:1 solution you'd need to add around 42L of water to it.

Density of 1:1 (vol) sugar syrup = 1.22g/ml, 48 brix

Density of 2:1 (vol) sugar syrup = 1.31g/ml, 64 brix

 

Using 1:1 in place of 2:1 given in recipe

Recipe calls for 100ml of 2:1 syrup

 

 

  1. Weight of 100ml of 2:1 = 100*1.31 = 131g
  2. Weight of sugar in 131g syrup = 131*0.64 = 83.84g
  3. Weight of 1:1 syrup required = 83.84/0.48 = 174.6667g
  4. Volume of 1:1 syrup required = 174.6667/1.22 = 143.1694ml

 

Hence 143ml of 1:1 syrup is required. (roughly 100ml x 1.4)

Ok so how much water to a 25 kg bag of sugar to make 1:1 syrup.

You university types can never answer in a simple manner :geek::what:

Thanks Otto; Grant I'll just get my calculator out.......and yes I couldn't have said it better Frazzle.

 

Frazzle I'd say 25kgs of water to 25kgs if sugar. 1 liter of water weighs 1 kg.

So Grant the maths is saying 43 mls of water per 100ml is required to make the conversion; or 43 liters......which makes the same total as Otto comes too.

So I'm going to go and add 43 liters of water into my container and turn the pump on to mix it up.........or maybe I just leave the lid off for a couple of hours and with the amount of rain falling today it'll do it for me

This university type was trying to answer the question that was asked:)

But yes, I could have added that a 1:1 solution would (as Jay and Yesbut point out) require 25L of water for a 25kg bag of sugar.

What would 25kg of sugar weigh at 2,000 metres above sea level?

The same as 25kg (25L) of water

Ah, but would 25kg of water still occupy 25L at that height ? Temperature difference ?

Yes. You are correct as usual. My bad.

@Jay you will need 41.66 L of water to that 100 L of syrup.

Looking at this conversation, you lot clearly need another bee season to start - stat.

 

And as Daley wisely said, the bees don't really care. I'm sure someone can bring out some research to say we need to feed xyz but hungry bees at this time of year will dispatch anything that is somewhere between 1:1 and 2:1.

Yeah, Air pressure adds to the "weight" of an object. Fairly insignificant when taking about pretty much most things. And not even reliably measurable without extremely accurate equipment. Something on the order of 0.1% IIRC

 

So yes, everything "weighs" a tiny bit less the higher the altitude, even less again if you are moving i.e. on an aeroplane where you are a fraction of the way into orbit. And things weigh less at the poles than they do at the equator for the same reason, closer to orbit.

And  weighing system contractors have to individually adjust scales according to geographic location, the gravitational field varies from suburb to suburb.

Actually, the pressure at the surface is 1bar give or take which is about 14.5psi. If your head is 8 inches across then that's about 50 square inches in area. So 50 x 14.5 converted to kg .... each of us is carrying over 300kg of atmosphere on our heads!

And can vary over time. I'm trying to remember an experiment i read about where they need to be so accurate they remap the gravity field around this experiment every now and again. (in a room)

If you were standing in a vacuum cylinder 8 inches in diameter with a piston above your head and nothing but the outside air pressure acting on it, then yeah, that's about right. I think you'd have bigger problems than 300kgs falling on your head in that situation.
