Cuprajake Don’t forget air weighs more than water

I now know why my lungs feel heavy. 🤣🤣🤣🤣👍👍👍👍

CoyoteOldMan

MediumRoastSteam That explains why my head feels heavy…

CoyoteOldMan

First steam of the day:

Boiler at 125 °C, 2-hole tip
185 grams of milk
Purge: 16 grams (+ a bit in the dry towel - but I’m not going to weigh the towel!)
Added steam weight: 28 grams
Total water drawn: 44 grams

LMSC I’m watching “The Strain” at the moment… if you have seen it, I think you’ll understand how my brain interpreted the .GIF at first sight. 😛😂🤣😂🤣

LMSC

CoyoteOldMan No, I haven’t seen it 😂

DavecUK

LMSC it’s good, I’m hooked… I got it too.

DavecUK Will put it on our watch list. Hope it is not like Stranger Things!

Accurately weighing is tough. Weighing the reservoir before and after the autofill is triggered might be the best way. Weighing the milk jug is easiest but you also weigh the air. I was surprised how much water increases in weight when it is carbonated, it gained about 6g.

I can’t tell if you are joking or not. I can inflate a balloon, and the balloon’s weight will be no different whether it’s inflated or not. (I actually tried it).

Why would it be different with aerated milk?

CoyoteOldMan

Rob1 Well… my steaming roughly doubles the volume of the milk (if I’m lucky and get it roughly right). Assuming it’s “air” at something close to boiler pressure (3 bar) but atmospheric temp (25 °C), which is the ‘maximum’ density (lowest temp in the possible range, highest pressure). This is about 3.5 mg/cm³ - or adding about 0.6 grams to my 180 ml…

I always keep my tyres 78% nitrogen filled.

Rob1

MediumRoastSteam

Nope, not kidding. Weighed 500g of distilled water on scales accurate to 0.1g, using an isi cream whipper (without the lid) screwed the lido on and used a couple of CO2 cartridges to carbonate it, depressurised, took the lid off and re-weighed and it had dissolved 6g of about 14g CO2 used in the shaker.

It’s never something I’d considered with milk but thought it may have some minimal effect, obviously not tough.

CoyoteOldMan

DavecUK I try that too, but if I’m huffing and puffing when I inflate them with the pump I fear CO₂ concentration may change that 78% down to 77% or so…

The penny dropped just now for me! 🤣🤣🤣🤣🤣🤣👍👍👍

DavecUK

CoyoteOldMan Chuckle….

Of course it’s warm air…get enough in and the milk will float away.

I’m waiting for the house of commons to do the same after the recess

MediumRoastSteam

😊 - as I never know if people are serious or not, I used my aero latte and trebled the volume of 100g of milk inside a mug.

Milk in liquid form weight as it was poured out of the fridge: 100.00g.

Aerated milk weight, trebled in volume: 100.00g.

My head hurts now… from drinking the foamed cold milk! 🤣🤣🤣🤣

Cuprajake

Haha, I was joking 😅

MediumRoastSteam

Rob1 - interesting for sure Rob! Maybe it’s because it’s pure CO2 rather than a mixture of mainly oxygen and nitrogen (I.e: the air we breathe)?

DavecUK

Does this mean the longer we hold our breath, the heavier we get as CO2 builds up in our lungs?
