Re: Freezer question, your experience.

[AZ Nomad]

Let us know when you own a scale that has 5 sides in a vacuum and just the measuring part exposed to air.

My ATV tires take 3 psi yet they don't collapse! Read up on atmospheric pressure.

[tmclone]

Just wait until it comes out of rigor, of course.

[AZ Nomad]

It's 3PSI above atmospheric presure, dumbass.

[Doug Miller]

You're the one that needs to do the reading. Pressure gauges do *not* measure absolute pressure. Google the difference between psig and psia.

[Sqwertz]

Dude, I got one right here. But how do I use that to determine how much cold air I'm losing when I open my freezer?

[Sqwertz]

Yeah - What Larry said! You tell em Larry!

[AZ Nomad]

Simple. Evacuate the air from the room. Place freezer on scale, take reading. Open freezer door, let air out. Take another reading. Subtract second from first.

[Sqwertz]

What if you only have 40 minutes before your wife Bonnie comes home? (yet another movie reference - I'm on a roll)

[Doug Miller]

Larry has no clue about this; obviously, neither do you. I'll give you the same advice I gave him: *you* read up on atmospheric pressure. Learn the difference between psig and psia.

Here, I'll help:

You'd need a gravity scale. lol

Actually you lose it all... if your upright freezer is a 10 cuft model within 2 seconds of opening the door ALL 10 cuft of cold air drops out like it was a lead balloon (minus however much cuft your food occupies).

With a chest freezer in still ambiant air practically zero cuft of air drops out, even if there is no door. Most stupidmarket food freezers/fridges are chest type and have no door... instead they have a fill line and many have add-on deflectors to block air agitation. Food stores are more and more moving away from upright freezer/fridge units.

[Doug Miller]

So what?

Assume the freezer is half full (5 cu ft food, 5 cu ft air). Five cubic feet of food weighs about 250 pounds. Five cubic feet of air weighs about seven ounces.

Do you *really* believe that replacing seven ounces of zero-degree air with seven ounces of room temperature air is going to make *any* noticeable difference in the temperature of two hundred fifty pounds of food???

[Sqwertz]

All the freezers and fridges in the isles (100-150 feet long x 4 rows), milk/dairy, and beer (about 80% of the store) are clearly the upright variety (doors and no doors). The only exceptions are the chests in front of the meat displays.

[AZ Nomad]

Good thing they have windows so you can see what is inside before you use a sawzall to gain entry.

I prefer freezers with doors wether it is an upright or chest. Makes gaining entry so much easier than the sealed types.

[blake murphy]

it's somewhere between an r.c.h. and a metric buttload.

your pal, blake

[blake murphy]

this must be the one home repair problem duct tape can't solve.

Word!

[Larry]

At sea level, moron?

[AZ Nomad]

You can't possibly be that stupid. It's an act, right?

[Doug Miller]

Tire pressure gauges measure the difference between the pressure inside the tire and the pressure outside the tire.

Note in particular this sentence: "Psi is often used incorrectly instead of psig."
